Hi, I hope someone can clarify the statements in RFC3261 21.5.4.
If a server experiences an overload while processing an initial INVITE returning a 503 Service Unavailable with Retry-After header, how is the server supposed to deal with existing established sessions? The RFC3261 statements "SHOULD NOT forward any other requests to that server for the duration specified in the Retry-After header field, if present" seem to imply the server is left high and dry to deal with these on its own. Does it literally mean any other requests or is it depending on the type of SIP server, e.g. SIP GW, Application Server, SIP UE? While a UAC might want to abide by this requirement, maybe a proxy should allow at least mid-dialog requests proceed? This is probably a policy decision applied at a proxy, but just wondering if there is any BCP documenting this or have there been other discussions?
