No, Asterisk is a bad example for this case since doesn't provide SessionTimers functions and so. In fact I'm not suggesting a specific product, but you could try other B2BUA more SIP compliants and develop a B2BUA between OpenSer and gateways that implements SessionTimers. Of course it's not an easy task.

I want to depend only on Openser. OpenSer is a statefull proxy, it shouldn't control dialogs. With "dialog" module you can do things but obviously is not so complete as you need. > I believe I can be done with session timers, as you say.

The mos similar function in OpenSer is the registrar module sending NOT in-dialog OPTIONS to mantain NAT keepalive. > The thing is: > > What module's function to use to make the UAC send uns a "keep-alive" > whilst in a dialog every X senconds, setting a timeout for that keep-alive > to be sent and resetting it everytime it's received. There is not that function/module for now. :( -- Iñaki Baz Castillo [EMAIL PROTECTED] _______________________________________________ Users mailing list Users@lists.openser.org http://lists.openser.org/cgi-bin/mailman/listinfo/users
