Hi, RFC 3261 states that - "Note that request processing is atomic. If a request is accepted, all state changes associated with it MUST be performed. If it is rejected, all state changes MUST NOT be performed. "
Now a B2BUA is described in the RFC as a concatenation of a UAC and a UAS. If a call is established through the B2BUA, and an OPTIONS request is received by one side of the B2BUA, can it answer the request with a final response or should it wait for a response of the other side to the forwarded request ? If it waits, can it process additional overlapping requests? For example another OPTIONS or INFO?
