<div>Hi everyone.</div><div><br></div><div>I am facing a weird issue on a
 production setup, FS version 1.6.16~33~e6d643b-1~jessie+1 installed 
with deb from offcial repo, o.s. debian 8.</div><div>Scenario is pretty 
straightforward: call incoming from voip provider and routed to a sip 
phone, i have no nat between FS and provider, i have nat between FS and 
sip phone.<br></div><div><br></div><div>Provider sends INVITE with sdp (g711a + g729 + te) to FS<br></div><div style="margin-left:40px">FS sends INVITE
with sdp (g711a + g729 + te) to sip phone</div><div style="margin-left:40px">sip phone sends 180 RINGING back to FS</div><div>FS sends 183 SESS PROG with sdp (g711a + te) back to provider</div><div>PRACK and 200OK between provider and FS<br></div><div style="margin-left:40px">sip phone sends 200 OK with sdp (g729 + te) to FS</div><div style="margin-left:40px">
FS sends ACK to sip phone

</div><div>FS sends 200 without sdp to provider</div><div style="margin-left:40px">FS sends UPDATE with sdp (g729 + te + g711a) <br></div><div><div>provider sends ACK to FS</div><div style="margin-left:40px">sip phone sends 200OK (to the UPDATE) with sdp (G729 + te) to FS</div><br></div><div><div>At
 this point I have a bidirectional g711a rtp stream on the external 
profile. Instead on the internal profile i receive g729 from the phone but 
FS does not send any G729 stream to the phone.</div><div><br></div><div>I
 have run some tests: if i don't have G711a codec as 1st choice in the 
incoming INVITE, the audio is ok; both the provider and the phone 
support both G711a and G729, but sip phone always answer ONLY with its 
preferred codec (in this test, G729).</div><div>Generally speaking, if 
sip phone's preferred codec is different from the first codec in the 
incoming INVITE from the provider, i have the issue. Since the codec mix
 and order from the provider is not known, i cannot configure the sip 
phone accordingly.<br></div><div><br></div><div>On both external and internal profiles i have:</div><div style="margin-left:40px"><i>inbound-codec-negotiation = generous</i></div><div style="margin-left:40px"><i>inbound-late-negotiation = true</i></div><div style="margin-left:40px"><i>*-codec-prefs= G729, PCMA</i></div><div><br></div><div>FS logfile presents an error (loglevel: INFO, privacy data screened with *):</div><div><br></div><div>
