Only the higher end Polycoms support Siren7 and Siren14. I believe only the VVX and SoundStation IP phone support those codes.

I'm playing around with Asterisk and Polycom phones. I see Polycom supports quite a few codec. The usual ones and these: G722 Siren14.24kbps Siren22.32kbps Siren14.32kbps Siren22.48kbps Siren14.48kbps Siren22.64kbps G7221.16kbps G7221_C.24kbps G7221.24kbps G7221_C.32kbps G7221.32kbps G7221_C.48kbps I can get Asterisk to work with G722 and the sound is superior compared to uLAW. I tried to get it working with Siren7 and Siren14 but I cannot. It always says incompatible codec and what is this Siren14 and Siren22 with Polycom. Is this different to Asterisk's Siren7 and Siren14? Is this why I cannot get Siren to function? siren7 show version : Digium Siren7 Module Version 1.8.0_1.0.5 (optimized for barcelona_64) siren14 show version : Digium Siren14 Module Version 1.8.0_1.0.5 (optimized for barcelona_64) I found this document : http://www.polycom.com/global/documents/whitepapers/codecs_white_paper.pdf which is quite good. It sais: G.722.1. Also known as "Siren 7" G.722.1 Annex C. Also known as "Siren14" This doesn't explain why the Polycom G7221_C doesn't work with Asterisk's Siren14 G.722.1 doesn't work with Asterisk's Siren7 Am I just doing something wrong? Is my understand correct? So what is Siren14 and Siren22 on the Polycom handsets? What does that match to in Asterisk?
