<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">there are two basically problems i have with this patch.
1.) sending out keep alive messages on a sip reload will do this for all peers at once and imho this will happens everytime the keep alive timer fires. its basically the same problem for poke_peers but the scheduled time for repoking is spread and not just the same time interval. In a scenario with many peers this could even slow down the do_monitor thread cause of the big bunch of schedules to run in a very short amount of time.
2.) the string which will be sent to the peer should be also configurable cause i know atleast one router which ignores keep alive with a CRLF and still close the port but this could also be solved by using normal qualify instead.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">1) Unlike a qualify this doesn't create a dialog, do any SIP message creation, none of that. The scheduled function should run pretty darn quick and won't block nowhere near as long. I suspect even without spreading them out this could handle quite a few, but I can also spread it out.
2) Out of curiosity - what string would you use instead?</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch implements extremely lightweight NAT support, specifically sending a CRLF at a defined interval to keep the NAT mapping open. It does not use this mechanism to determine if the remote server is available or not, that is the trade off.</pre>
