the call towards sip:68465283 at   contains only
G.729 in SDP offer, so the remote side turned it down. You can use the
"absolute_codec_string" variable to enforce the G.711 codec on the
other side.

Also, late negotiation is enabled by default in the SIP profiles. You
may want to disable it, so that each leg negotiates the codec more
