Because that is a ubiquitously-used mechanism in SIP -- if the attempt to reach one contact point or destination fails, the call is then routed to another, lower-priority, destination. E.g., if you don't answer a call on your desk phone, then the call is routed to your voicemail recorder. > And in case the proxy wants to do it upon receipt of a response > "destination doesn't exist", why should a 6XX avoid it? Um, you have read RFC 3261 regarding the handling of 6xx responses, haven't you? _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
