Polycom RPD Issue with new firmware

[Anonymous]

Hello team,

May I know is there any known issue of new version RPD?

When I use version "RPD-release_3.7" with my Yealink T49G, video from the other side can't be seen.

Downloading to previous version "RPD-release_3.3_50871" or ealier version solve the issue imediatelly.

Pcap trace has been attached.

In your packet trace:

DynamicRTP-Type-97 and 123 packets are coming in from 10.15.151.2

 Is it possible that traffic is being dropped between the packet capture point and the endpoint?

You might provide a PCAP file of a good call for comparison.

I attach packet of 3.3 Thanks,

To confirm my interpretation of the scenario:

Polycom RPD 3.3 H.323 calling Yealink SIP T49G, video received fine from T49G

Polycom RPD 3.7 H.323 calling Yealink SIP T49G, video failing from T49G

Packet captures are from the Polycom RPD end but where exactly, the Desktop PC or a intermediary switch/router/firewall or gatekeeper?

What do you have doing the H.323 to SIP conversion? The gatekeeper the RPD is registering to?

The packet captures appear similar with TCP/UDP port numbers changing as the calls advance thru the alloted port ranges.

Yes, you are correct. Changing protocol to SIP doesn't make a difference. They call through ip address, no gatekeeper registered. I also attach RPDlogs, may be some error info can be found. Thank you!

If you have purchased a license for your RPD then you should probably open a ticket with Polycom.  They might be able to determine the difference between RPD 3.3 and RPD 3.7 that is causing the issue. May be simple as a configuration setting.

In the RPD log files, the 3.7 calls contain numerous 'SendKeyFrameRequest, GDR but the frequency is too high.'s and the 3.3 calls do not.  There may be some problem with the incoming video frames and the RPD 3.7 interpreting them.
