[Freeswitch-users] registration fails after several hours - FS problem?

I should mention that I did not have this problem with an SPA9000 PBX (asterisk based) for over two years so FS may be pickier about upnp and/or nat, or just better at it exposing a problem in the router.

I made different changes to the gateways to test different things. One failed after 17 hours, the other two stayed up.  What did not work:
added <variable name="sip-force-expires" value="30"/> to the directory entries as suggested.
set the gateway expire times to 30 seconds.

What worked (could be coincidental) for the two gateways that stayed up: I Added <param name="aggressive-nat-detection" value="true"/>

I originally setup FS to use the static ip by setting external sip/rtp to just the static ip (no autonat:) and ran with -nonat but I could not get incoming calls. The only way it worked was to use autonat:1.2.3.4. The router has 1 static public address and 1 dynamic external IP, this is the root of the problem, upnp only tells FS about the dynamic ip  Will keep this thread up-to-date for anyone who may be in the same boat someday. Thanks again for looking at the trace.

I was looking into aggressive-nat- detection since the internal profile status always shows the right external static IP but the nat_ap status always shows the dynamic ip. Crossing fingers/etc since this problem is 85% of time (weeks!) into FS changeover. Thanks!
