It's amazing that such a fundamental session configuration topic is not really well specified (explicitly, detailed, unambiguous) in RFCs 3261 & 3264. Just wondering ... -Albrecht > -Original Message- > From: sip-implementors-boun...@lists.cs.columbia.edu > [mailto:sip-implementors-boun

Iñaki, This is probably far from obvious. The reason for creating new ones was because for anonymization purposes you probably don't want to keep using the same one. It would have been better to have an explicit mechanism to request when you want a new one, but that didn't fit into the model w
