Hello,

Hi,
As Stefan pointed out in my prevoius email, I started playing around
with DSM. What I'm trying to do is a b2bua just for signalling, no
media. I modified the test_b2bua dsm file a little because I didn't
want the announce, but when sems receives an INVITE it always replies
488 could not find compatible payload! :-O
Here is a part of the DSM file:
import(mod_dlg);
initial state START
enter {
set(reply_request="0");
set(connect_session="0");
};
transition "Received BYE in START" START - hangup / stop(false) -> END;
transition "on INVITE" START - invite -> runinvite;
state runinvite
enter {
dlg.reply(100, "Trying");
B2B.connectCallee("sip:[email protected]",
"sip:[email protected]");
};
transition "Let's wait" runinvite - -> waitconnect;
state waitconnect;
##################################
I set connect_session to 0, but I suspect it still tries to process
audio... Am I doing something wrong?
have you set
run_invite_event=yes
(which defaults to no) in dsm.conf ?
Without it, the session is accepted with 200 immediately and only with
onSessionStart your DSM is executed. With run_invite_event=yes, your DSM
is started two times: first at onInvite, then at onSessionStart.
connect_session only has effect with run_invite_event.
Stefan
P.S: I think run_invite_event is somewhat strange implementation of
this. If you can come up with a nicer method how this could be
implemented or specified, i am open to suggestions or patches.
Regards,
