Yes; unless specifically restricted by the event package, draft-ietf-sipcore-event-rate-control, or similar RFC. However doing so can complicate some things such as retargeting. > Does the specification mention otherwise? The following indicates how to respond when such behavior leads to the requests being delivered out of order. RFC 3261 section 12.2.2: "If the remote sequence number was not empty, but the sequence number of the request is lower than the remote sequence number, the request is out of order and MUST be rejected with a 500 (Server Internal Error) response." _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
