From: =?utf-8?q?I=C3=B1aki_Baz_Castillo?= <[EMAIL PROTECTED]> Hi, when calling to two SIP/PSTN gateways, if the callee doesn't reply in XX seconds then the gateway sends me a "480 User Unavailable".
Well, I think is much better using "408 Timeout", isn't it? 408 is used consistently to mean IP-level timeout in sending a request from one element to another. It is also defined to be returned by a UA when the time specified in "Expires" has been reached. (In theory, two different error codes should be defined for these two situations, but that has not been done.) However, in a ring-no-answer situation, it is more common for an upstream proxy to send a CANCEL to the UA/gateway, in which case the UA/gateway provides a 487 response to the INVITE.
