Workaround: Start the search in a different location or avoid use of Unicode characters
>127 in directories.
42027 In certain scenarios, the time-stamping in log files of a SoundStation IP 7000 that is used
as a secondary/slave device is incorrect.
Workaround: As of SIP 3.1.0 the occurrence of this issue only relates to the treatment of
Daylight savings Time settings.
44764 SRTP processing may cause performance degradation with certain video/audio codec
combinations on the VVX 1500.
Workaround: If SRTP is being used, limit the video bit rate to 384 Kbps.
46997 Camera brightness adjustment does not work between levels 3 to 6 on the VVX 1500.
Workaround: No workaround is currently available.
48905 Jitter parameter is not correctly computed on the SoundStation IP 6000/7000 as per
RFC3550.
Workaround: No workaround is currently available.
52141 Daisy-chained SoundStation IP 7000 phones sometimes become stuck during software
upgrade.
Workaround: Pressing any key on the phone will continue the upgrade.
52142 Video connections with CounterPath Eyebeam client on the VVX 1500 do not work if
H.263-1998 codec is selected. This was experienced with Eyebeam version 1.5.19.5
build 52345.
Workaround: Try using a different codec. Try other versions of Eyebeam client as some
do work.
53514 H.264 calls to an HDX9002 device using an MGC 50 Gateway using H.320 result in lip
sync issues (applies to VVX 1500).
Workaround: Set the call for transcoding on the MGC.
54027 The receiving phone does not re-invite with a new key at the half-life of the key life-time.
Workaround: Ensure that both ends use the same key life time so that the sending
phone will initiate a key re-negotiation.
54028 Key changes do not function correctly when multiple crypto suites are enabled.
Workaround: Configure a single crypto suite on the phone.
54321 The VVX 1500 does not receive video (does receive audio) when calls are initiated from
a Tandberg C20 (running 2.0.0.191232) device using SIP.
Workaround: No workaround is currently available.
54799 The VVX 1500 transmits H.264 QCIF video to Tandberg MXPs in H.323 calls.
Workaround: Set the video bit rate on the VVX 1500 to 512 Kbps to avoid the issue.
