美股市场的几种违规交易操盘手法总结
美股市场的几种违规交易操盘手法总结几个月前美国SEC及FINRA针对目前美股市场的违规交易进行了严格审查，影响到了很多国内的DT公司，很多交易员因此也给封闭账户，停止交易，并连带公司一起遭到SEC的罚款。
因此在短短的几个月以来，又出现了很多以此种交易手法为主的公司及交易员遭到了打击------倒闭的倒闭，分流的分流，转型的转型，改行的改行。
很多交易员不明白到底哪几种情况属于违规交易。
现统计整理如下，希望各交易员引以为戒。
违规交易：1 ： Spoofing:反复挂单，撤单，大量的短时间内摆放假单子，意图在短时间内改变买卖单量的对比，刻意人为造成LEVEL2所反映出来的买卖方信息，造成了欺诈市场的行为。
主要做法为动量股票多层压单法。
2：laxxxxyering:摆很多单子，刻意打压价位，影响市场，也归属为欺诈行为，属于严重违规。
对于此举处罚力度很严重。
主要做法为暗盘信风交易法。
3：Wash sale :简单的说也就是自己打自己的单子，不管是刻意的还是无意的，都属于严重违规，会导致账户被关闭。
为此很多交易员的手法都受限于WASH SALE的限制，特别说明一下我公司的很多账户都是已经向美国总部申请解除的，请各个交易员注意一定要注意自己的操盘风险。
出现该违规情况，主要是由于股票突变成交，交易员由于时间造成的影响，导致惊慌失措，直接造成自己成交到了自己的单子。
4：Cross trading：交易员之间的互相打对方的单子，也就是刻意的进行交易，最简单的例子就是之前的ARCAMPL的互打行为，以赚取大量的佣金为目的，值得说明一下的就是：目前市场上再次出现了一个新的通道----PHLX 及BYX，这两个通道都是可以通过交易员之间的互打而实现赚取佣金的目的。
因此暂时总部没有给各个分公司开通此两个通道，主要也就是为了避免再次出现ARCAMPL这个尴尬的情况。
5：Oversell：也就是不可以空的股票，进行非法做空。
这个因为不用多讲了。

Release NotesV Series and VSX® Systems, Version 9.0.1Polycom is pleased to announce the release of version 9.0.1 software forPolycom® V Series and VSX® systems. This document provides the latestinformation about the V Series and VSX systems and version 9.0.1 software.For more information about updating software and enabling system options,refer to the Installing Polycom V Series and VSX Software and Options documentby navigating to /support/video and clicking on thename of your product.What’s New in the 9.0.1 Release?VSX software version 9.0.1 provides a fix for an issue associated with thepassword encryption feature introduced in VSX software version 9.0.When a VSX system with Security Mode enabled was upgraded from aprevious software version to VSX software version 9.0, the room password nolonger worked. As a result, the Admin Settings became inaccessible even whenthe previously used room password was correctly entered on the system. What’s New in the 9.0 Release?VSX3000A and V700 customers may experience flicker and unusual behavior ontheir displays when upgrading to version 9.0.1. This is normal behavior and it iscritical that the system NOT be turned off during this process. The completeupgrade should take approximately 2-3 minutes over IP, and after the upgrade iscomplete, the system will restart automatically.For a VSX system with password encryption and Security Mode enabled, Polycomrecommends that you delete the room password or disable Security Mode beforedowngrading from software version 9.0 or later to a build prior to version 9.0.Some features are only available on the 128MB systems (V700, VSX3000A,VSX5000, VSX6000A, VSX7000s, VSX7000e, VSX8000).Refer to the System Information page (System > System Information) for thememory size of the system, noted as (64) or (128) after the Model name.July 2008Lost Packet RecoveryVersion 9.0 provides improved dynamic bandwidth allocation (DBA) and new error concealment for Polycom Video Error Concealment (PVEC) using Lost Packet Recovery (LPR). The new DBA algorithm downspeeds the call to reduce packet loss to a manageable level under normal operatingenvironments. This allows LPR to recreate the remaining lost packets.For complete protection against network packet loss, enable both LPR and DBA; the combination of DBA and LPR provides virtually error-free video. On average, visible video disruptions can be expected only once every 5 minutes for average packet loss scenarios of 3% or less, and more often for packet loss scenarios higher than 3%.To use LPR, both the near-end system and the far-end system must have the Enable PVEC setting enabled. If the far-end system does not have this setting enabled, the near-end system uses PVEC rather than LPR.SIP Signaling of DTMF DigitsVersion 9.0 supports signaling for DTMF digits during SIP calls, as specified by RFC2833.Lost packet recovery is only available on the 128MB systems (V700, VSX 3000A, VSX 5000, VSX 6000A, VSX 7000s, VSX 7000e, VSX8000).Points to note about LPR:•LPR is available on H.323 calls only; it is not supported on SIP or H.320 calls.•LPR is available in point-to-point calls only; it is not supported in multipoint calls.•LPR is not available on Avaya networks.Supported DTMF digits include the numbers 0–9, the asterisk (*), and the number sign (#).This feature is not supported in the following scenarios:•Calls with AES encryption enabled •Multipoint callsMicrosoft® Windows® Vista Support for SoftupdateWith version 9.0, you can use the Softupdate application with the Microsoft®Windows® Vista, Windows XP, or Windows 2000 operating system whenupdating the software on VSX systems and V Series systems.Indication for Basic ModeIn version 9.0, the Call Statistics screen indicates whether the VSX system orV Series system is operating in Basic Mode.To view the Basic Mode indicator:1.Go to System > Diagnostics > Call Statistics.2.Select .3.View the Call Type field.“(Basic Mode)” is appended to the data in the Call Type field when theVSX system or V Series system is operating in Basic Mode.AES Encryption IconWith version 9.0, the VSX system or V Series system continually displays anicon whenever AES Encryption is enabled on the system.The icon behavior is as follows:•The icon displays as locked throughout the call when AESEncryption is enabled on the near-end system and the call is AESencrypted.•The icon is absent when AES Encryption is not enabled on the near-endsystem.•The icon displays as unlocked throughout the call when AESEncryption is enabled on the near-end system but the call is not AESencrypted..The call may not be AES encrypted because the VSX system or V Series system isoperating in Basic Mode or because one or more of the far-end systems do nothave AES Encryption enabled.Password EncryptionVersion 9.0 includes enhanced password encryption for meeting, room, and remote access passwords.When Security Mode is enabled, the VSX system stores all meeting, room, and remote access passwords using the SHA-1 algorithm rather than using clear text.Password DisplayMeeting, room, and remote access passwords now always appear as a series of asterisks as you type them into a configuration screen or login box.To enter numbers in a password field, use the remote control number buttons. To enter letters in a password field, press Keyboardon the remote control.Re-entering to Confirm PasswordsIn some cases, you must now re-enter passwords to confirm them.•When updating or entering a meeting, room, or remote access password,you are now prompted to re-enter the password to confirm it.•When enabling Security Mode, you must now enter and confirm a new room password, even if a room password is already in use on the system.•When enabling or disabling Security Mode, you must now enter and confirm each meeting, room, and remote access password that is set.The password encryption feature is an enhancement to Security Mode. Because Security Mode is only available on the 128MB systems (V700, VSX 3000A,VSX 5000, VSX 6000A, VSX 7000s, VSX 7000e, VSX 8000), password encryption is also only available on the 128MB systems.When a VSX system with Security Mode enabled was upgraded from a previous software version to VSX software version 9.0, the room password no longerworked. As a result, the Admin Settings became inaccessible even when the previously used room password was correctly entered on the system. This has been corrected in VSX software version 9.0.1.For a VSX system with password encryption and Security Mode enabled, Polycom recommends that you delete the room password or disable Security Mode before downgrading from software version 9.0 or later to a build prior to version 9.0.You cannot change the roomsw , sw , meetingpassword , websw , and securemode configuration variables when using uploaded profiles (Utilities > Profile Center ) through the system’s web interface, even if the uploaded profiles contain one or more of these variables. These configuration variables are also excluded from downloaded profiles.New Version of People+Content™ IPPeople+Content ™ IP version 1.2 is now available on the Polycom web site, on the Downloads page for each VSX system. Version 1.2 includes performance improvements and fixes to address minor technical issues.Corrected Issue in Version 9.0.1The following table lists the issue corrected in version 9.0.1.Corrected Issues in Version 9.0The following table lists issues corrected in version 9.0.The People+Content IP option key is included with the VSX 8000 and is optional for all other VSX and V Series systems. For information about purchasing thePeople+Content IP option, please contact your Polycom distributor.For information about using People+Content IP to display content, refer to the Getting Started Guide for your product.IssueDescription Security Mode When a VSX system with Security Mode enabled wasupgraded from a previous software version to VSX softwareversion 9.0, the room password no longer worked. As aresult, the Admin Settings became inaccessible even whenthe previously used room password was correctly entered onthe system. This has been corrected.IssueDescription API Changes made using the audiotransmitlevel commanddid not result in any command feedback. This has beencorrected.Using the timediffgmt command to provision the time zoneon the VSX system did not work correctly. This has beencorrected.Directory New directory entries created in a new local category werenot visible when you tried to view them the first time, until youmoved around in the screen. This has been corrected.Global Management System The Management Servers list (System > Admin Settings > Global Services > Management Servers) displayed URLs for the Global Management System™ even after theVSX system or V Series system unregistered from the Global Management System. This has been corrected.When the Global Management System became unavailable, the VSX system or V Series system no longer displayed the global directory entries even when Save Global Directory to System (System > Admin Settings > Global Services > Directory Servers) was enabled. This has been corrected. Using the Global Management System to provision the time zone on the VSX system or V Series system did not work correctly. This has been corrected.Interoperability Avaya When V500 systems, VSX systems, or Polycom HDX systems registered to the 8700 ACM and attempted to call into the Polycom RMX, the call sometimes connected without video. This has been corrected.Interoperability Nortel SIP calls placed between VSX systems or V Series systems and the Nortel Multimedia Communication Server (MCS) Multimedia PC client did not connect. This has been corrected.When a call was transferred between VSX systems orV Series systems and the Nortel MCS Multimedia PC (MMPC) client using the “Announce Caller” feature, the resulting call included audio but not video on all systems. This has been corrected.When a caller used the “Call Park” feature during SIP calls between VSX systems or V Series systems and the Nortel MMPC client, the other system in the call was not put on audio and video hold. This has been corrected.During a SIP call between VSX systems or V Series systems using the Nortel MCS, using the unHold Telnet command to remove the hold status on a call did not remove the hold status on the system that initiated the unHold command. This has been corrected.Using Telnet to register VSX systems or V Series systems with the Nortel MCS did not work. This has been corrected.Interoperability SoundStation VTX 1000In voice over ISDN calls using the SoundStation VTX 1000® conference phone and a VSX system, the button for hanging up the audio call did not display on the SoundStation VTX 1000. This has been corrected.Issue DescriptionInteroperability TANDBERG In ISDN calls with a TANDBERG MPS800 and VSX7000s or VSX7000 system at call rates of 384kbps and 512kbps, the VSX7000s or VSX7000 system did not maintain 30 frames per second when sending H.239 content. The frame rate also sometimes did not return to 30fps after the H.239 stream was stopped. This has been corrected.The payload number and clock rate for far-end camera control of TANDBERG systems were incorrect onVSX systems. This has been corrected.SIP When a VSX system called a SIP account logged in toWindows Messenger, messages sent to the VSX systemfrom Windows Messenger were interpreted as video calls.This has been corrected.SNMP The SNMP MIBs (Management Information Bases) on theVSX7000 and VSX7000s systems displayed two identicalifIndex values. This has been corrected.Issue DescriptionIssue DescriptionUser Interface On the VSX7000, VSX7000s, VSX7000e, and VSX8000systems, the Camera Control setting (System > AdminSettings > General Settings > Serial Port) was unavailablewhen the RS-232 Mode setting was set to Camera PTZ (orSony PTZ in previous versions). This has been corrected.While performing an ISDN software update (System >Utilities > Software Update), the VSX system allowed theuser to attempt to place a call, and the VSX system wouldthen crash. This has been corrected.The ping test is now available for use with both H.323 andnon-H.323 devices (System > Diagnostics > Network >PING).After you registered a gatekeeper through System > AdminSettings > Network > IP > H.323 Settings, VSX systemswith IP only or with ISDN disabled were displaying truncatedE.164 extension information on the home screen. This hasbeen corrected.Web Interface Using both single-byte and double-byte characters whenentering a new Directory entry caused the Localized Name tobe corrupted when it was saved. This has been corrected.The complete list of local and global directory entries was notalways displayed when accessing the directory (Place a Call> Directory). This has been corrected.After installing People+Content IP on a PC and connectingPeople+Content IP to the VSX system or V Series system,pressing the Graphics button on the remote control in theweb interface (Tools > Remote Control) did not send thecontent and displayed an error message. This has beencorrected.If you used the web interface to join a conference with ameeting password, the meeting password you entered wasalso set as the meeting password for your system. This hasbeen corrected.SIP registration status was not displayed in the system’s webinterface. This has been corrected.On the VSX3000, the System Information page (Tools >System Information) of the system’s web interface displayedthe memory size of the system as (128) rather than as (64).This has been corrected.Feature LimitationsThe feature limitations for version 9.0.1 are listed in the following table. If aworkaround is available, it is noted in the table.Feature LimitationAES Encryption You cannot activate encryption during a call.Analog Phone Incoming POTS (analog phone) calls will not be reported inthe Recent Calls list.API If you execute the button home command after clicking theCamera button on the VSX remote control or after executingthe button camera command, the VSX system does nottake you to the home screen until you execute the buttonhome command a second time.Attempting to execute the sleeptext set command whileusing an opening parenthesis but no closing parenthesis withthe accompanying text causes the text to be defaulted to notext and fails to return an error message indicating illegalparameters.The prilinebuildout set command does not work forvalues -7.5 and -22.5.The vcstream register command does not work from theAPI interface.The remotecontrol enable all command is not working.So if remote control is disabled from the API interface, youmust restart the system to enable it again.The gatewayprefix set and gatewaysuffix set APIcommands accept special symbols as value parameters.Entering another gatewayprefix set or gatewaysuffixset command with any value parameter forces the system torestart.Currently API interfaces do not report when the systemrestarts.The callencryption command supports the followingsubcommands: whenavailable|required|disabled|get.Each of these returns a yes|no value.The gatekeeperip get command feedback may includeextraneous data after the IP address.The chaircontrol set_password command does not work.Use the command callinfo all instead of display call.If rollover dialing occurs (for example, the systemautomatically redials a number as ISDN if it fails to connectswhen dialed as IP), the system will report an “ended” eventfor each failed attempt.The chaircontrol set_password command does notwork and therefore prevents setting the password throughthe API.Feature LimitationAPI If the control application issues a vcbutton play commandwhen a system that had been playing content is in theprocess of stopping content, the system may return the error“vcbutton [play|stop] command ignored due to currentprocessing". If this occurs, restart the system to restorevcbutton [play|stop] functionality.The screen name returned by the getscreen API commanddoes not always match the name displayed in the userinterface. When programming and calling a screen, pleasenavigate to that screen in the user interface and then use thegetscreen API command to determine the API name for thatscreen.If you send a command to change a setting on a userinterface screen while viewing that screen on the monitor,you might have to leave the screen and return to it to see thechange take effect.Using the set parameter to set values with the snmpadmin,snmpcommunity, snmpconsoleip, snmplocation, andsnmpsystemdescription API commands restarts thesystem without prompting the user.When requireacctnumtodial and validateacctnumare enabled, the user is prompted for setaccountnumberwhen attempting to dial a call through the API. When the userenters the setaccountnumber command, an “error:command not found” message is returned and the callcannot be dialed. A workaround is to disable therequireacctnumtodial and validateacctnumcommands.The chaircontrol req_term_name, chaircontrolset_term_name, chaircontrol view_broadcaster,and chaircontrol set_password API commands donot function correctly.In VSX software version 9.0.1 and later, you can no longeruse the adminpassword set API command to change theroom password on the system.The streamannounce command does not work and doesnot set or get the streaming announcement setting.The callpreference sip yes command does not restart64MB systems when you enter “y” to “restart system forchanges to take effect. restart now? <y,n>”.Audio Playback volume is not adjustable on the start-up languageselection screen.When one VCR or DVD player is connected to a VSX6000or VSX7000 to play content into the call, and another isconnected to record the call, audio from the VCR or DVDplayer content is not recorded.Calls placed at a call speed of 64kbps connect at G.729A8kbps audio rather than at G.722 16kbps audio.Boot UI Downgrading the boot UI on the VSX3000 or VSX3000Amay damage the boot UI and cause the VSX system tobecome unusable.Calling On a VSX8000, if you make a POTS call to an analog or cellphone and then try to call the number again from the RecentCalls list, the call is dialed as voice over ISDN if ISDN Voiceis listed ahead of Analog Phone in the Call Preferencedialing order. To work around this behavior, set AnalogPhone ahead of ISDN Voice in the Call Preference list.If the VSX5000 has the Preferred Dialing Method setting(System > Admin Settings > Network > Call Preference)set to Auto and the Call Type is changed from IP to SIP, theVSX5000 may display an error message and may notsuccessfully dial and connect a call with a SIP site. Aworkaround is to change the Preferred Dialing Method toManual before changing the Call Type to SIP.Cameras The V700 incorrectly displays an icon for the second cameraoption if you press Far twice on the remote control during acall.There is no way for a user to get camera control for a camerathat is set to the content channel.The Camera Calibration screen will always be displayed forthe VSX7000e and VSX8000, even though automaticcamera tracking only works with a PowerCam™ Pluscamera.To avoid a “keystone effect” in which the video imageappears tilted, make sure that the VSX5000 camera ispointed perpendicular to the subject.Chair Control Selecting Acquire Chair on a VSX7000 that can hostmultipoint calls may disable Discussion mode view.Closed Captions Closed captions cannot be sent through a gateway.Conference on Demand Conference on Demand calls to ISDN sites may fail when dialed from an H.323-only system. To work around this issue, provide the full international number, including country code, for ISDN sites.When using a VSX system to initiate an all-IP or mixed IP and ISDN, multipoint, H.264 Conference on Demand call using Polycom PathNavigator™, you may be unable to send content and may instead receive a “Far site does not support dual streams” message after pressing the graphics button on the remote control. A workaround is to use H.263 instead.Feature LimitationConfiguration Do not change the VSX system monitor setting while sendingcontent.Factory camera presets (press the Near button and then thePreset button on the remote control) are not available on theVSX5000. However, you can program presets after youreceive the system.Directory System names using double-byte character sets (DBCS)should be edited in the directory using the system’s webinterface.Dual Monitor Emulation Content is displayed incorrectly on the VSX 3000 when it is configured for dual monitor emulation and is receiving content during a 1472 kbps call. Workarounds include disabling dual monitor emulation on the VSX 3000 or reducing the call speed to 512 kbps.Far End Camera Control Far-site camera presets that you set with the V700, VSX3000, and VSX5000 may not work.Gatekeepers When the primary gatekeeper becomes unavailable, theVSX system may require up to 5 minutes to successfullyregister to the alternate gatekeeper. When the primarygatekeeper becomes available again, the VSX system mayrequire up to 10 minutes to successfully re-register to theprimary gatekeeper. If the gatekeeper (such as the PolycomPathNavigator) is set to routed mode and the VSX system isin a call when the gatekeeper goes down or comes backonline, the call will be disconnected.Gateway Calls In calls through a gateway, selecting a far-site camera sourcethat is not being used shows frozen video from the previouscamera source, instead of a blue screen.H.323-H.320-H.323 gateway calls placed using a valid TCS4extension delimiter (##) between the dial string and E.164extension fail to connect to the second gateway and,ultimately, to the system being called. A workaround is to dialthe call without ## and the E.164 extension, allow the call toconnect to the second gateway, and then manually enter theE.164 extension of the system you are calling.Global Management System Global Management System 7.0 does not display H.320 information for V500 systems.The Global Management System Call Statistics screen shows up to only three sites in an internal multipoint call, even when more than three sites are connected.Global Management System provisioning of the Primary and Secondary Call Types is not supported.Feature LimitationH.264The following conditions apply to H.264:•On VSX systems other than a VSX8000 using TVmonitors, H.264 is supported in point-to-point calls up to768 kbps. On systems that use an interlaced camera, thetransmit preference at 768 kbps is H.263 Pro-Motion.•On VSX systems other than a VSX8000 usingsingle-monitor VGA, H.264 is supported in point-to-pointcalls up to 512 kbps.•H.264 Pro-Motion is supported in point-to-point callsbetween VSX8000 systems up to 1.4 Mbps.•On VSX8000 systems, H.264 is supported in calls withup to four sites.H.331When broadcast mode is enabled on a V.35 system and theaudio protocol is set to G.711U, the far site might hear a popwhen the call is disconnected.In an H.331 call between two VSX systems with H.264 videoconfigured and with People+Content turned off, neither sitecan send content to the other site. To resolve this problem,the site sending content should enable People+Content.When enabling People+Content in the H.331 configuration ofa V.35 system, you must also enable H.239 to send content.Interoperability ADTRAN TSU 100With V.35 systems, VSX systems can crash when in a call at 1280 kbps.Interoperability Aethra In H.323 calls between a VSX8000 system and the Aethra Vega Star Gold version 5.1.35, content is sent from the Aethra system as a single stream and no far-site video is displayed on the VSX8000, even though the VSX8000 displays the dual stream icon.In H.263 calls between a VSX system and the Aethra Vega X7 version 11.1.4 beta, the Aethra Vega X7 may constantly repeat the caps exchange if the Aethra Vega X7 has annex J and I enabled on its H.263 cap set. As a result, theVSX system call log may show constant capset exchange requests from the Aethra Vega X7, and the VSX system video may display constant video updates throughout the duration of the call.When a VSX5000 calls the Aethra Vega Star Gold version 6.00.0022 at 336k over ISDN, the VSX5000 may show only the near-site video after AES encryption is confirmed.Feature LimitationInteroperability Avaya AES Encryption is not supported while registered to the Avaya Communication Manager (ACM).When a V500 system or VSX system attempts to call another V500 system or VSX system through the ACM, the near-site system continues to ring if the far site rejects the call and has Auto Answer Point-to-Point Video or Auto Answer Multipoint Video set to No.NAT is not supported for systems registered to the Avaya Communication Manager.While connected to the ACM, telephony features are not supported to systems behind a neighboring gatekeeper. Cisco PIX does not pass through Annex H which is required by the ACM. V500 systems and VSX systems will not connect calls across a Firewall that does not pass Annex H. Call forward busy/Don’t Answer does not work with a multipoint VSX system set to forward (registered to the ACM).Avaya's IP Softphone (IPSP) with video set to manual will not negotiate video with sites registered to a neighboring gatekeeper.In calls placed from a V500 system or VSX system, thefar-site system name may show a neighboring gatekeeper, such as “PathNavigator,” instead of the actual system name. G728 k and G722.1-16 k audio codecs are not available when registered to the ACM.When an iPower™ system can host multipoint calls and calls an Avaya IP Softphone (IPSP), a V500 system using Avaya, or a VSX system using Avaya, the call does not connect.In multipoint calls, far-site names are displayed as the system name entered on the ACM for each system rather than as the local system name.V500 systems or VSX systems configured for NTSC and using the ACM may incorrectly send 4CIF video (normally a PAL format) while sending content.The Gatekeeper IP Address field is cleared and you must manually re-enter the Gatekeeper IP address after setting Use Gatekeeper (System > Admin Settings > Network > IP > H.323 Settings) to Off and then changing it to On.Feature LimitationInteroperability Avaya When a V500 system or VSX system that is registered to the ACM is in a call with a V500 system or VSX system that is registered to the Polycom PathNavigator, audio is not transmitted to the system that is registered to the ACM. When Use Gatekeeper (System > Admin Settings > Network > IP > H.323 Settings) is set to Specify with PIN, the system may attempt to register with a different gatekeeper when an incorrect PIN is entered.If the V500 system or VSX system is registered with the ACM but is subsequently disconnected from the network, when network connectivity returns, the V500 system orVSX system may not re-register with the ACM automatically.Interoperability Cisco PIX In an H.323 multipoint conference, when a VSX system hosts the multipoint call and is located behind a Cisco PIX 6.3.4 firewall among systems with H.239 enabled, the V Series system or VSX system outside of the firewall may not receive video when other sites connect. To avoid this, disable H.239 on all sites.V Series systems or VSX systems with AES encryption enabled cannot connect using H.460 with Cisco PIX 506.V Series systems or VSX systems with H.239 enabled may not be able to send or receive content using H.239 with Cisco PIX 515. A workaround is to disable H.239.Interoperability Codian When a VSX system places a 768kbps or higher call to the Codian bridge, the VSX system may become unresponsive and must be restarted. A workaround is to place a call at 512kbps or 384kbps.Interoperability iPower In H.323 multipoint calls using AES encryption, with a VSX system hosting the multipoint call and iPower and PVX™ systems as sites, iPower will not transmit video if PVX is the second site. To avoid this issue, call the PVX system first. When an iPower dials into a VSX7000e that is hosting the multipoint call and another VSX system joins the call, the iPower will disconnect. To work around this issue, connect the iPower as the second or later participant in the conference.Interoperability LifeSize When using the internal multipoint capabilities of theVSX8000 to connect a LifeSize Room system to a multipoint SIP call, video freeze may occur on the far-end systems.In a point-to-point SIP call between a LifeSize Room system and another system, both systems have distorted audio. This occurs both when the LifeSize Room system places a call and when the LifeSize Room system receives the call.Feature Limitation。
