I am trying to understand how call waiting is done in SIP. Assume the following scenario:
A and B are already involved in a call. C calls B, and B has call waiting. B's phone supports call waiting and notifies B of the incoming call from C. My question is the following: Will C get any indication that the call to B is a call waiting call? Or, in other words, is there any standard way in SIP to indicate in the backwards direction (from B to C) that the call is a call waiting call? If there is no "standard" way, is there a "de facto standard" convention that is used? Thanks.
