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:

but I am looking for a quick and dirty fix, where I restrict all to ULaw.
Thank you. A.C.
