I agree with Maxim here. You should try to classify traffic to various destinations and configure application timers (possibly in a table) to these destinations.A logging mechanism can help you fine tune these values and find new destinations that have high RTT and hence are timing out. 2009/1/3 M

[Sip-implementors] Retry intervals

2008-12-31 Thread Dale Worley
How should we handle retry intervals for resending SIP requests which have received no response? RFC 3261 prescribes doubling the retry interval each time, starting with an interval (T1) which is an estimate of the round-trip time of the network, and ending with 32 times that, for 6 retries total.
