Hello, As a B2BUA what is the expectation when it is sitting behind a forking proxy (IMS Application Server) and it is sending back multiple early dialogs back.
1. It should ideally send it back transparently to ingress i.e. creating multiple early dialogs at ingress leg too. (UAC should be capable of supporting early dialogs) 2. Doing inter-working with ingress and rather than sending multiple early dialog toward ingress it should send new offer in UPDATE. (Though in this case UAC should support UPDATE method in early dialog). In the above scenario if Pre-condition is been expected then will there be any change or it should be same. As per my understanding forking proxy should handle, in this scenario, once the pre-condition has been exchanged & resource reservation has been done. AS should not send multiple early dialog towards B2BUA. Though i am trying to find reference in RFC or 3GPP standard but not yet able to find any. Your expert inputs are much appreciated and if it can be provided in some reference to standard it will be very helpful. -- Thanks, Varun Bhatia _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
