Hi,

Can I know the Call ID of a UAC / UAS who has been registered on th eproxy server?

I need to send the MESSAGE to the Particular "UAC" but I do not know the Call ID ?

There is no INVITE nor Call Established.But I need to send IM to that particular UAC.

As Far As I Know, Call id is mandatory , Hence I need to know the Call id from the prosy server.

How should I proceed?

Thanks and Regards.

Abhijit
