[Freeswitch-users] mod_opal - call charged before H.225 connect

[Tihomir Culjaga]

hi Anthony,

it is somewhere here:

         switch_status_t
FSConnection::receive_message(switch_core_session_message_t *msg)


anyhow, i will open an issue jira of course.


I understand your financial point of view, but anyhow while the entire world
is wants sip and trying to move to sip, the reality is quite different. The
majority of voice traffic exchanged via IP is still H323. This means a
working SIP - H323 interworking is really needed... pity nobody wants/has
time to work in this direction to produce a decent mod_h323.
