Make sure the codec used by the Polycom
will be only g729 via the phone's web interface, as far as I remember
Polycom will try always to use ulaw or alaw first unless it is
configured to use only or as first choice the g729 codec.

Hi, I'm experiencing some problems with polycom phones, asterisk and g729 codec.
As I understand, between polycom and polycom i can use g729 without
license at all as long as I'm using codec_g729.so module (i'm using
the Open Source Implementation (
because it's pure pass-thru and there's no transcoding).
My sip.conf has the following options:
mailbox=202 at default
so i force the voipuser to use g729 as main codec. The problem comes
when i try to connect to other polycom phone with the same config as
voipuser. The CLI shows the following:
Sep 19 18:37:38 NOTICE: chan_sip.c:3691 process_sdp: No compatible codecs!
show modules doesnt show codec_g729.so but if i try to load it i get this:
Unable to load module codec_g729.so
Sep 19 18:39:16 WARNING: loader.c:305 __load_resource: Module
'codec_g729.so' already exists
Anyone had this issue?
If you need more information, feel fre to ask for it :)
Thanks a lot!
