Hi,
I have a doubt on how to indicate Calling Party Category (CPC) parameter in an INVITE message. I had gone through draft "draft-mahy-iptel-cpc-00.txt" that says that cpc should be included as the uri parameter of the from header. An example is given as :-
INVITE sip:[EMAIL PROTECTED] SIP/2.0 To: "Bob" <sip:[EMAIL PROTECTED]> From: <tel:+17005554141;cpc=payphone>;tag=1928301774
In the example, cpc is represented as parameter of the from uri. Suppose CPC has to be used with a sip uri, how should that be included. Is it :-
From: <sip:[EMAIL PROTECTED];cpc=payphone>;tag=1928301774
or is it From: <sip:+17005554141;[EMAIL PROTECTED]>;tag=1928301774
I have a feeling that the second option is correct. I wanted to confirm whether my understanding is correct.
AFAIK neither answer is correct. This is a concept that has representation in a tel uri but not in sip.
Is there any other draft or rfc that says how the cpc paramter should be used in SIP protocol other than the one i referred.
Don't think so.
