Hello,
there are two options:
1) use a dedicated instance of ser on another port that writes all
requests directly to sems; forward calls via t_relay_to_udp
2) set user_prefix_separator=+ in sems.conf, then sems will reply with
a contact in the form of voicemail+<user>@host which you can then filter
in your ser.cfg. have a look at docs/ directory in sems

Hi,
I have a strange problem with stateful processing using t_relay and t_newtran.
For normal routing I use t_relay but all sems modules require the usage of
t_newtran, e.g.:
if ( !t_newtran() )
{
sl_reply_error();
};
t_write_unix("/tmp/am_sock", "voicemail");
The problem now is how to handle BYE and CANCEL messages for deestablishing
connections. For the echo server (reachable at 4242(a)192.168.11.1) I use the
following code for getting back transaction and closing socket to sems:
if ( uri=~"^sip:4242@" && ( method=="BYE" ||
method=="CANCEL" ) )
{
if (!t_newtran())
{
sl_send_reply("500", "could not create transaction");
break;
};
if( !t_write_unix("/tmp/am_sock", "bye") )
{
t_reply("500", "error contacting sems");
};
break;
}
This works fine. But how can I do this for voicemail? The uri will not be
changed so I can't destinguish between BYE for a normal and a voicemail
connection.
All other destinations do not use t_newtran (and no socket to sems) so simply
t_relay is used for BYE and CANCEL messages.
The whole ser.cfg is attached below.
Regards and thanks for your help,
Dennis
