No MUST behavior has been defined for the situation; it is not a hold. The UAS received a request to communicate with a non reachable/responsive location. If the UAS responds prior to the connection attempt, the UAS will likely send a 200 response with SDP reflecting typical offer/answer rules. The non reachable/responsive location may subsequently cause the call to be released; however the UAS might be more forgiving if some media attributes (such as "inactive" and "sendonly") were used. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
