Using the From Display Name as CallerID is dangerous IMHO. Imagine a phone receives a call with From: From: "111111" <sip:[EMAIL PROTECTED]> Also imagine that the phone renders "111111" as CallerID (so the human expects 111111 is calling him). But the human can't answer now and decides to call later by pressing "Missed calls" in his phone menu over the received call. The INVITE the phone will generate as this RURI: <sip:[EMAIL PROTECTED]> so the human is, in fact, calling to 222222 (while he expect being calling to number 111111). -- Iñaki Baz Castillo _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
