Is this not true?
No, because it is not guaranteed that [EMAIL PROTECTED] routes to the UA instance that C was using in the call with B. It may end up at some other device, or e.g. go to voice mail Regards, Jeroen _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
