I'm trying to get 2 VVX 600 endpoints (firmware 5.4) using G.722.1C or Siren14 between eachother.

 

In Asterisk I can enable G.722.1C which seems to be the same as Siren14 according to http://www.polycom.com/company/about-us/technology/siren.html. The codec priorities in the extension on asterisk show siren14.

 

The VVX 500 and 600 though support G.722.1C but apparently not Siren14.  I'm confused since these are apparently different names for the same codec?

 

Has anybody been able to use either Siren14 or G.722.1C with Asterisk with these phones?

I'm not positive but it looks like maybe the phones aren't sending the correct codec in the SDP when G722.1C is enabled.

 

I got G722.1 working.  In that case I got the following in the invite

m=audio 2302 RTP/AVP 102 127
a=rtpmap:102 G7221/16000
a=fmtp:102 bitrate=32000

 

With just G722.1C enabled I get

m=audio 2298 RTP/AVP 0 8 127
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000

Hello eli,

welcome back to the Polycom Community.

The next step would be to open a service ticket with Polycom as advised in your older posts as well.

 

Did you ever get around to do this and if yes what was the ticket number starting with 1- ?

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Thanks Steffen, I did open a case for the other issue.  Unfortunately no progress has been made on that ticket yet although I have gotten a couple of responses.  I don't seem to have a Polycom ticket number in the email chain.  I opened the ticket through Telephony Depot, it looks like their ticket number is 68138.  I haven't had any direct communication with Polycom on that one yet.
