Subject: [Sip] outbound: recovery in case of flow failure

From: "Jeroen van Bemmel" <[email-masked]>

Suggestion for section 5.3 (Edge proxy forwarding) and 6.2 (registrar forwarding): When a flow is found but fails upon trying, the registrar / edge proxy could send back a '480 Temporarily Unavailable' response, with a Retry-After equal to the maximum time a flow recovery would take (ie about 29 seconds for UDP, 120 seconds for TCP)

This could help the caller in deciding to retry after giving the callee enough time to restore its flow

Regards,

Jeroen
