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.

You should be setting the req freq to a low number on the outbound gateways
The examples you showed had a series of inbound reg

also set expire-seconds to 30 in your gateway xml


The problem is if you are not constantly sending traffic to the box
the nat mapping will go away.

If you are in production you should be using a static ip with a static
mapping, any trouble you are having is your own fault for playing with
fire.  The best we can do is tell you how to keep it contained.

I made the change. I had no idea the settings for the inside phones effected nat for the outside sip accounts. 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!

add

to the <variables> section of your <user>

you have it at 600 and the nat mapping is timing out while the 600
seconds is ticking away

From the TSP:
"I have enabled the SIP trace on your account. We are not currently seeing
any registration attempts to your account within the last 15 minutes. Please
restart FreeSwitch so that registration attempts begin again. Thank you. ".
So FS is not getting past router.

I ran the global trace during the problem and it is
at http://pastebin.freeswitch.org/14324 . You can find "rnktel", "acctone",
"accttwo", "acct3". The trace includes phones since it was global. I am
using:
   <param name="ext-rtp-ip" value="autonat:my-static.ip"/>
   <param name="ext-sip-ip" value="autonat:my-static.ip"/>
I tried dumping nat and removing the autonat: above and using -nonat but
that did not work, registration proceeded but no calls inbound.

Whoops, I am using an IP address for at least one gateway so that is not the
problem:
They look outbound to me and I am using dns for 2 and an IP for one so that
is not the issue. I was able to get FS to clear this up by doing "nat_map
reinit" which is why I think this is a nat problem. I will do the trace you
mentioned. I will plug an ip address into one of the gateways to see what
happens, they all fail at once. Thanks for responding!

I really need help on this as I have weeks into this problem. I thought I

and no way to make/get calls until I restart FS. I did this:

1. log 7

2. sofia profile xxxx siptrace on   for each profile/gateway

3. restarted router

All three did not solve the problem. The trace and log produced no
additional lines which is why I am wondering if FS has a problem since the
trace shows no SIP activity.

3 gateways with 2 ITSPs

2 DSL/WAN lines, 1 static and 1 dynamic

I am using autonat:1.2.3.4 in internal and external profiles. 1.2.3.4 is the
external static ip.

sofia status profile ... has the right ext ip

nat_map status shows the dynamic (wrong) IP

I tried starting with -nonat but that was worse

the only way to fix is restart FS.

I read the wiki on external nat, auto_nat and everything else many times.

Thanks Mario
