Method dmAddCallDialog

SIP/SIP2Interface.cpp:155–172

For outgoing [client] invites the invite should have the local tag already and is put in the map using the localtag. For incoming [server] invites, we add the call dialog initially without the local tag, then later add the localtag to the key when we get the ACK.
