20554
2. Cascade In an ISDN Master-Slave cascading conferences, if participants are connected to the conference before connecting the links between the conferences using blast dial-out, morphing occurs on some endpoints during the connection process.
3. Cascade In Cascaded Video Switching conferences with an ISDN link, FECC occasionally does not work.
20299
4. Content All the participants Status becomes Faulty Connected when PVX endpoints send Content.
21569
5. COP When the first active participant is disconnected and the video of other participants is muted, participants view background colors.
19288
6. CP MCU status changes to Major for 30 seconds when connecting 32 endpoints at a line rate of E1 to a CP conference.

7. CP In a CP Quad Views conference with more than 12 H.264 participants, the frame rate may decrease.
20553
8. CP Fragmented Video can occur during speaker changes in CP H.264 conferences.
21311
9. Database In the Participants database, when you Copy As a participant template and then modify this template without prior pasting the copied template, the system forces you to save the original template under a different name.
21142 Save the participant under a new name, and then, if required, delete it from the database.
10. Encryption In a Video Switching encrypted conference with more than 75 participants and set to a 768KB line rate, the Audio+ card may crash.

13. FECC FECC does not work between an IP endpoint and an MPI (DTE) endpoint.
20401
14. FTP FTP service on XPEK may stop working, which affects system functions, such as prevent the Logger Diagnostic Files from opening, causing the MGC Manager application to close.
20433 In the IP
Gatekeeper CON (Conference On Demand) does not work with the MGC-25. With the MGC-50/MGC-100/
MGC+ it works with asserts.
20477
16. Gateway When connecting conferences using the Gateway when you move a participant to and from a conference, no video is seen.
19469
17. Gateway When calling from H323 endpoint to an EQ placed on MGC V6 (used as an MCU) through MGC V7 (used as GW H323->H320), the call will fail.
20232
18. General When moving a participant from one conference to another, the “First to join”
IVR message is heard twice.
19515
19. General The 'Auto_Redial' parameters in 'confer.cfg' file are not updated.
20897 Require MCU restart in order for changes to take effect.
20. General Creating a conference with parameters
"enable invite" and "encryption", the invitees are rejected.
21097
21. General SilenceIT algorithm does not
automatically mute participants placing their line on hold, hence background music is played to the conference.
21960
22. H.264 In Video Switching conference set to 21207 Table 6: Pending Issues (Continued)

Corrections, Pending Issues and Limitations
24. ISDN After upgrade to version 7.5, the MCU loses the ISDN clock source
configuration. In Faults file there is no message about “NO CLOCK
SOURCE”.
20685 Reconfigure the ISDN clock.
25. ISDN ISDN endpoints fail to move to Video Switching conference when the line rate of the destination conference is higher then the line rate at the initial conference.
20932
26. IP+ In a mixed system with ISDN and IP, when the clock is set to ISDN and you set the source of the ISDN span to Null, the IP+ card may stop responding.
— Set the system.cfg (MCU_CLOCKING
section) flag:
INTERNAL_CLOCK
= YES prior to setting the ISDN span to Null.
27. IP+ After participants disconnect from a conference, the LED on the card is still On (Active).
17890
28. IPower IPower fails to send content in a CP conference set to Auto, H.239 P+C and dial out.
21066
29. MGC Manager In the H.245 Properties dialog box, when H.239 is used, P+C is indicated instead.
20468
30. MGC Manager Wrong indication in the MGC Manager when Moving IP endpoints from one Video Switching 384 Kbps to a Video Switching 512 Kbps conference, the participant appears connected when they should say secondary.
20933
31. MGC Manager On an XPEK MCU, when extreme packet loss occurs, the MGC Manager can loose connection with the MCU.
21519
32. MGC-25 The Resource Report does not display IP capacities for line rates of 256 Kbps and 512 Kbps.
18307
33. MGC-25 Moving 3 IP participants from CP Quad View to a CP COP Quad View
conference fails on the MGC25.
20926 Move
participants one at a time.

35. NTP When the MCU connects to the NTP server for a time calibration, connection problems occur and 15 hour time deviations result on the MCU.
20619
36. On-line Help On-line help is not updated in version 7.0.X.
15670
37. PSOS When sending files to the MCU, the MCU displays a “Bad Connection”
status indication. When the download is completed the status indication reverts to “Normal”.
17914
38. PSOS The Backup and Restore processes take more than 20 minutes to complete.
18869
39. PVX During MCU dialout, the PVX endpoint connects as “Secondary” when the dial out call is set to H.263 and the endpoint VGA Encoding is enabled.
21115
40. SIP An IP Video Switching conference set to 256Kb with many SIP participants may crash the IP+ card.
19547
41. SIP After a SIP connection failure, deleting SIP participants from the conference fails.
20788
42. SIP When changing the Refresh SIP registration in the IP Service to 10 seconds, the LCS proxy rejects the MGC and registration fails.
21191 Set the Refresh SIP Registration to more than 10 seconds.
43. SIP LCS proxy does not work with Automatic SIP-Factory settings.
21319 In the LCS proxy, define
static-route rules using IP board (format:
*@IPAddress) 44. SSL The MCU occasionally disconnects
from MGC manager when using a secured port (port 443 - SSL).
20880 Reconnect to the MCU.
45. SNMP SNMP MIB2 sections: interfaces, at, ip, icmp, tcp, udp, egp transmission are not supported in XPEK.

49. Video Switching
In a Video Switching conference when the speaker changes, all ISDN parties accumulate R-Synch Video Loss and are indicated as “Faulty” in MGC Manager. On average Video is impaired for 1 second.
21068
50. Video Switching
During the start of Video Switching conference, poor video can appear for several seconds.
21061
51. VoIP In a CP conference with VoIP phones, the Audio+ card can crash when using the G.729 Audio Algorithm.
19609
52. VTX1000 For future use.
53. XP In XP installations, the Setup is halted when the Logger file is full.
19660 Clean the logger file before installation.
54. XP After upgrading the MGC Manager to version 7.5, the MCU’s re-start takes longer (up to 2 additional minutes). This is due to the Microsoft new service pack synchronizing with the MCU’s software.
