But in my case, I don't need trascoding because every chanel is in GSM
and voicemail has gsm sound files.
And for the moment, my Asterisk is not connected to the PSTN, so there
is no trascoding gsm-to-PCM or to analog.
So I think gsm is a good choice for my scenario, do you ???
Thanks a lot !!!

GSM is greate! there was a miss understood.
if you transcode more than 90 in a core 2 duo you get a bad audio
GSM to G729 or G711 to G729.
G711 to GSM is ok, but you should test it.

Do you think GSM codec has poor audio quality ???
Because I've made some tests among softphones connected from different
cities of my country and the audio was good to me.
Maybe GSM is a good choice.

out there is a free for educational and no commercial G729 lib for asterisk
you can use it to test in a non-comercial system.
the digium lib is much better. if you have more than 30~60 phones
transcoding inst a very good idea.
i made my self a test on a core 2 duo 64 bits 2GB of ram a test transcod

Yes, there is a WAN among the hardphones and my Asterisk server.
I know the GSM bitrate is about 31 Kbps.

Thanks for your comment about codecsI tell you I can't use G.711
because I use a WAN link, and this is a wide band codec.

g723 is supported by Ast
Dear all, I have Asterisk 1.4 with SIP. I have a voicemail implemented
with GSM sound files.
The problem is I have IP phones Utopix HyperPhone 202 which support
only G.729a/u and G.723.1 high/low, but not GSM.
If I choose G.729A the "pass-throu" calls among users are OK, but
