What are my options when I am looking for a quick fix for the following situation: My in/out traffic is on a few different carriers. Carrier A is sending this SDP on first INVITE, offering PCMA first and PCMU second: v=0 o=Sonus_UAC 17329 9183 IN IP4 206.165.95.165 s=SIP Media Capabilities c=IN IP4 206.165.95.166 t=0 0 m=audio 24330 RTP/AVP 8 0 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=sendrecv a=maxptime:20 Freeswitch does the right thing by RFC 3264 and selects PCMA but then negotiates PCMU on the outgoing leg. Then, it drops out of the data path and I have another B2BUA in the middle, that can't translate. Can I make FreeSwitch reply with PCMU? [ Am in North America, with pretty much all my traffic on ULaw] I found this suggestion: http://wiki.freeswitch.org/wiki/Codec_negotiation#Late_Negotiation_.28requir... but I am looking for a quick and dirty fix, where I restrict all to ULaw. Thank you. A.C.
