Re: Polycom M100 trial install/Win7 - only able to make H.323 audio only calls

Thanks for the response.

The testing has been to primarily Tandbeg/Codian equipment.

The 64K was probably just the audio being negotiated, the test I made was at 384KBPS.

The Codian bridge and Tandberg endpoints do support H.264 - I tried multiple systems and received the same results.

Is there anything else to try?  Is it a specialized version of H.264 proprietary to Polycom?

We have successfully used Polycom PVX in the past but now have Win7 systems we are testing the version M100 with those systems.

Another test is to see if M100 is compatible with Tandberg VCS Expressway solutions.

Any comments would be appreciated.

Sorry but I have to stand corrected when I said m100 only supports H264. It actually will support H261 and H263.  I was thinking of CMAD and the RPM.
However looking at the interoperability chart in the m100 release notes there is no mention of  Codian MCU and  the endpoint listed is the Tandberg C20 which would be in a point to point call.
 
If it is not listed it does not mean it will not work only that we have not done any testing.  So compatibility is unknown.
 
To answer your question, we do not use a proprietary H264. Actually I do not believe there is such a thing. H264 is an industry standard and there are no annexes to confuse the caps exchange.
 
Release notes are below.
