Re: [Users] Differentiate INVITEs

If anything, all I need to do is add a check for the address in the SDP for an INVITE. Some phones do allow you to configure a MOH URL but not all do. I'd like to come up with something that will work for me and other people in the community on any phone. Plain 'ol generic SIP is probably the only way (this is how Asterisk does it so seamlessly). If I implement this with SEMS I will have the same problem. As you said, I still need to "catch" the on-hold re-INVITE from the phone and send it to SEMS. I already have Asterisk servers (and I'm much more familiar with Asterisk than SEMS), I might as well try to send the intercepted (for lack of a better term) re-INVITE to Asterisk (and have Asterisk process it as a normal call) - not to SEMS (although it would probably also work for SEMS in place of Asterisk). It looks like textops might be able to do this in a hack-ish sort of way... I'll try it and see what happens but I would certainly like something cleaner. What would need to be added to OpenSER to support checking for this? Even exposing a few of the values (perhaps as pseudo-variables) from the SDP on an INVITE would be a great start. I'm sure that this is more of a dev list question but I thought that I would ask here first... Thanks again for the reply! -- Kristian Kielhofner
