Thanks to all who responded! I find P-Asserted-Identity to be the best solution and here is why.
1. Because of its simplicity it is very likely already supported by major telecom companies. 2. What Michael suggested may be used but has serious limitations as pointed out by Chandra. In addition, it assumes that both A and B will have to use 2 stacks (for 2 dialogs) which is not as elegant as solution with a single dialog. 3. 2nd Jerry's recommendation is to follow draft-ietf-sip-connected-identity-05. I find it to be an overkill and is intended for non-trusted networks which is not my case. Zarko ____________________________________________________________________________________ 8:00? 8:25? 8:40?
