Thanks But i am little confused as from RFC 3261 Section 10 page 58 it says
Call-ID: All registrations from a UAC SHOULD use the same Call-ID header field value for registrations sent to a particular registrar. If the same client were to use different Call-ID values, a registrar could not detect whether a delayed REGISTER request might have arrived out of order. which means for registering userA for port 5060 and userY for port 5051 in different REGISTER request In that case both registrations will have the same call-id On 11/1/06, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > > > > *"Divya Sachdeva" <[EMAIL PROTECTED]>* > Sent by: [EMAIL PROTECTED] > > 11/01/2006 01:01 PM > To > [email protected] cc > > Subject > [Sip-implementors] Register Request > > > > > > > I hve a question regarding REGISTER request Can one UA register to the > same registrar with two names in order to > redirect different users to different ports? > > [Balaji Says] > Yes...
