please set the environment variable TPORT_LOG=1 to log the sip traffic
inline.
then capture all of the console output reproduce your issue
before you try the call, please enter the command "console loglevel debug"
at the CLI
also, just to be safe, examine your dialplan for any instances of
bypass_media and examine all of your sip profiles for the
inbound-bypass-media param.
