The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network environment. The engine tier can send, receive and process various messages. The state tier can maintain in-memory state data associated with various SIP sessions. The SIP server can support converged HTTP and SIP modes of communication. An application session can be established for allowing the association of an HTTP session with a SIP session such that data can be exchanged between them. This association can be broken and reestablished with new application sessions such that various SIP and HTTP clients can join and leave new sessions. An API can be provided to enable various associations and method calls for the application session.
