Re: [Freeswitch-users] Codec Mismatch Because of Different Frame Size

30 Sep 2010


      It's the git version from yesterday evening:

    freeswitch@internal> version
    FreeSWITCH Version 1.0.head (git-633f193 2010-09-29 16-52-43 -0500)

Jan,
as far as I know, FS does not care about the ptime.
The behaviour you are noticing is weird.
Can you tell us which version you are using ?

I'm using the following configuration:
vars.xml:
<X-PRE-PROCESS cmd="set"
data="global_codec_prefs=G729,PCMU,PCMA,G723,G7221@32000h,G7221@16000h,G722,GSM"/>
<X-PRE-PROCESS cmd="set"
data="outbound_codec_prefs=G729,PCMU,PCMA,G723,GSM"/>
external.xml (my standard sip profile):
<param name="inbound-codec-negotiation" value="greedy"/>
<param name="inbound-late-negotiation" value="false"/>
<param name="disable-transcoding" value="true"/>
With this configuration I want to restrict the allowed codecs, force the
usage of G729 as first choice, if available and to minimize the calls
with transcoding.  I don't want to force the usage of a specific 
frame size.
Now a lot of calls get rejected with "incompatible destination" by
FreeSwitch, because the frame size of the incoming calls differs from
the Freeswitch default (mostly 20 ms), see the debug log below.
Is this the intended behaviour? If it is, how can I circumvent it? Do I
have to list every codec with every possible frame size in the
global_codec_prefs list?
Thank you in advance
