I agree with Inaki. We did exactly the same. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Romel Khan Sent: Friday, August 12, 2011 7:05 PM To: Iñaki Baz Castillo Cc: [email protected]; Paul Kyzivat Subject: Re: [Sip-implementors] Response code sent by proxy to caller when UAS not registered
When a call comes into our system, we do look up whether this number is ours or not. If it is not our number, we would return SIP 404. Then we check the presence server to see if the device is registered. If it is not, we send back SIP 480. A peer of ours is sending back SIP 403 in this case, which does not seem to fit with the specs in any manner.
