A SIP load balander is in fact a SIP proxy (generally in stateless), so it must add's a Via header. > 2. SIP Response should traverse SIP-Loadbalancer or the SIP-Server can > send it directly to respective SIP-Client. The resopnse should traverse the load balancer. This is by SIP definition. Imagine two cases: 1) Load balancer ---> SIP UDP ---> UAS In this case the UAS would reply to the Via sent-by in case it's equal to the load balancer IP address. In case the Via sent-by added by the load balancer is a hostname then the UAS would add "received=REAL_SOURCE_IP_OF_LOAD_BALANCER" to Via and sent replies there, 2) Load balancer ---> SIP TCP ---> UAS By definition a UAS msut reply using the incoming TCP connection. -- Iñaki Baz Castillo <[EMAIL PROTECTED]> _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
