Hi, In RFC 16.7 processing response (point 6. page 109) it states that "If there are no final responses in the context, the proxy MUST send a 408 (Request Timeout) response to the server transaction."
Can someone help me understand this situation. When a proxy recv a INVITE from caller , it forwards it to the callee's proxy. Now if the callee is not responding ( no answer condition i.e. after 180 Ringing received by callee's proxy from callee).It sends a '408 Request timeout' to caller's proxy. A> Is this correct to send '408 request timeout' in a no answer condition.. If this is correct then how can we differentiate if request actually timed out or it was ( no answer/ busy condition). B> When the caller's proxy get a 408 Request timeout ( after 180 Ringing), is it fine to send 480 Temporary unavailable back to the caller?
