random disconnections Freephoneline spa2102

[pmicho]

Hi,
I have a spa2102 ATA with a freephoneline account. I ramdomly get disconnected (yellow light off). On the same ATA my other sip acount with another provider never disconnects. Can someone help. I have attached screenshot of my configuration.

Japanese Aerospace eXploration Agency? You hiring?

Anyway, no 'obvious' issues.

Things to try:
Reduce the registration interval (try 600 or 1800)
Turn on NAT Keep-Alive

Try a more standard SIP port? (I believe the officially supported ranges for FPL are 5060-5080, or 6060-6061)

ensure Port Forwarding of the chosen SIP port to the ATA.

As this is a Sipura based model I would try......

Nat Mapping Enable Yes
Nat keep Alive Yes
Ext. Sip Port 5060 (just to be tidy ... this is the default anyway)
Use Outbound Proxy in Dialog NO
Turn STUN on and point it to stun.callwithus.com

Check that the ATA is getting the external IP address correctly.

Thanks for replies. Here is my new configuration. It seems to hold, but I will see if I loose the yellow light again.
By the way, I forgot to say that I has a second line on the same ATA with a Acanac account. I turned it off. Could this have had something to do?

Now my yellow light seems to stay on. But in my FPL settings, at sip status I get "disconnected"

This configuration works. I also disabled other line on same ATA.
Thanks for help
