3.2 Outstanding Issues
The following issues will be fixed in a subsequent release.
Note: Polycom has switched to a different issue tracking system which has caused the
reference numbers in these release notes to be different to earlier versions. When the
issues are addressed the numbers in this release note can be used to track in which
version the issue is addressed.
• 24398: No Layer 2 QoS support for signaling protocol (TCP)
Workaround: The default QOS parameters will still be used for TCP signaling
packets, and these may be specified in the sip.cfg configuration file. Layer3 QoS
settings are supported.
• 24805: Cannot answer an incoming call while directory is being saved
Workaround: None.
• 26615: Subnet mask forces all packets through gateway when not using DHCP
and when using the wrong subnet mask for the network class in use, for
example using 192.168.X.X addresses with a 255.255.0.0 subnet mask
Workaround: Use the correct subnet mask.
• 26920: Centralized conference fails due to RTP port being slow to open in
some cases
Workaround: None.
• 27469: Local Conferencing on IP4000 phones is disabled if G.729 is in the
Codec preference list
Workaround: Disable G.729 as a Codec option on the phone by setting
voice.codecPref.IP_4000.G729AB=””
• 28508: Phone crashes after receiving high call rate (4 unanswered calls every
18 seconds)
Workaround: Reduce the incoming call rate.
• 29344: HTTP Digest Authentication does not work on IIS
Workaround: Use a different form of authentication, a different protocol or a different
server
• 29946: Log files are not uploaded if an Apache 2.0.X boot server requires
authentication
Workaround: Turn off authentication or use version 1.3.3X of the Apache server.
• 30086: Boot servers running explicit FTPS are not supported
Workaround: Use implicit FTPS or HTTPS.
• 30371: Pattern generator for tones does not work well for the case of a single
repeating chord
Workaround: Start the pattern with a short period of silence then the desired initial
chord. Loop back to the desired initial chord instead of the initial silence.
• 30903: Packet Loss statistics ‘jump’ if calls are transferred.
Workaround: If using the packet loss statistics for troubleshooting purposes make a
note of the Packet Loss value after the transfer and apply a correction based on this
to subsequent calculations.
