Hi,
I haven't tried your b2b_connect plugin, but your use of
connectSession() in both caller and callee session seems strange to me.
If you look at AmB2ABSession, it calls connectSession in both caller and
callee session at the right place, so if everything goes up to the logic
of that base classes, then you don't need to call it in your dialog class.
Also, note that onSessionStart is called right after onInvite - so it
tries to connect the session right after processing the invite, but
there is no connector (callee session not yet there), so this will fail.
I think, you are missing to call acceptAudio (which sets up RTP stream);
this needs to be called when the positive reply comes from callee leg
(see how it is done in AmSession::onInvite, which you are correctly
overriding). That would be if you receive a B2ABConnectAudio event.
maybe like this:
void b2b_connectDialog::onB2ABEvent(B2ABEvent* ev)
{
if (ev->event_id == B2ABConnectAudio) {
// delayed processing of first INVITE request
onInvite(invite_req);
}
AmB2ABCallerSession::onB2ABEvent(B2ABEvent* ev);
}
I have used this b2b with media only in the way to first accept the
call, play something to the caller, and then call the callee with
connectCallee. But, if you tweak it a little further, it should work in
your way as well.
