Hi All, I have some doubts related to SIP multicasting.
1. Is it possible to run multiple registrars with different domain names (say D1 & D2) in a network? 2. Assuming (1) is possible and an UA that belongs to D1 sends multicast REGISTER request to login. What will be the response of D2 on receiving multicast REGISTER? I think D2 should not reply because, if the response from D2 reaches first at UA, login will be failed since UA will take the first response according to RFC 3261 Section 17.1.3 "If a request is sent via multicast, it is possible that it will generate multiple responses from different servers. These responses will all have the same branch parameter in the topmost Via, but vary in the To tag. The first response received, based on the rules above, will be used, and others will be viewed as retransmissions. That is not an error; multicast SIP provides only a rudimentary "single-hop-discovery-like" service that is limited to processing a single response." Can anyone clarify this please?
