I’ve done some testing and found out my router’s udp timeout is 60 seconds (Samsung iBG1000).
So if I don’t use keep-alives shorter than 60 seconds there’s a good chance I’ll lose a connection and the default qualifyfreq in asterisk is 60 seconds.
Fortunately XLite/eyeBeam uses a 30 second keep-alive.
LinkSys SPA 8000 has a configurable NAT keep-alive interval.
But I have other devices that I don’t think are as flexable.
Is there any way to upgrade AsteriskNow/1.5 (which uses asterisk/1.4.24) to do qualify more often than 60 seconds?
I know asterisk/1.6 has a qualifyfreq option.
I’ve seen a patch here voip-info.org/wiki/view/Asterisk+sip+qualify but I hate trying to recompile stuff.
How easy would it be to upgrade to asterisk/1.6 or would FreePBX blow up?
