There are lots of things one needs to do to engineer a truly resilient, scalable, fault tolerant sip based system. Handling data replication and distribution is one of them. There are many known techniques for this which can be applied, none of which are sip specific at all. The sip spec will not provide answers for these things for you. You need to do them yourself. -Jonathan R. --- Jonathan D.
