Its probably not even what you think it is, Its probably trying to generate ringback and failing. On Wed, Jul 13, 2016 at 7:35 AM, Vladislav Ivanov <deforceczt@gmail.com> wrote:
Hello,
I have an issue with codec negotiation, seems to me that freeswitch is trying to transcode g729 to g729 annexb=no for some reason, even when I have different codecs available?
I'm bridging 2 calls, with profile settings: <param name="inbound-late-negotiation" value="true"/> <param name="disable-transcoding" value="true"/> and dialplan: <action application="set" data="inherit_codec=true"/>
with global codec: <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMA,PCMU,G729,G723"/>
here is invite and 183 progress message:

After that I get error message:
2016-07-13 11:29:11.136011 [ERR] mod_g729.c:102 This codec is only usable in passthrough mode! 2016-07-13 11:29:11.136011 [ERR] switch_core_io.c:1434 Codec G.729 encoder error!
and freeswitch sends CANCEL to B-side leg.
Maybe I have missed my settings, but if codecs "mismatch" shouldn't freeswitch choose g711 a/u and not try to "transcode" the codec?
