[Freeswitch-users] No Media on bridging two external calls

[Michael Collins]

Recommend viewing the SIP trace on working vs. non-working calls. See if
you can figure out where the audio is attempting to go on the non-working
call as that will be your first clue on what to do next. Depending on your
preference you can turn on SIP trace right at the command line or use a
tool like tcpdump and then analyze in Wireshark. If you're relatively new
to SIP traces then I'd use tcpdump + WS since it's a bit easier to read.
