[asterisk-users] Polycom wideband codecs?

[m***@mstvp.com]

Doing a little research before Friday's Voip Users Conference call with
Dan Behringer.

Are any of the newer Polycom wideband codecs implemented in v1.6?
Specifically, G.722.1 or G.722.2?

Thanks,

Asterisk 1.6 has passthrough/record/playback support for G.722.1
(Siren7) and G.722.1 Annex C (Siren14). There is no support for G.722.2,
I'm not sure that is even a Polycom codec.

We are working on producing transcoder (codec) modules for these codecs
as well, so hopefully in the near future we'll be able to transcode
between these codecs and the others already supported.

Which Polycom supports G.722.2? I think they are only supporting G.722,
G.722.1 and G.722.1C right now.

Could someone enlighten me, what is the difference (the result part
that matters, not the spec)?

In this case I had, in my hurry this morning, simply confused G.722.1C
and G.722.2. These are both low bitrate wide bandwidth codecs.

They are also known by the Polycom marketechure nomenclature of Siren7
and Siren14. G.722.1 supporting 7 KHz passband, while G.722.1C support
14 KHz passband.
