[asterisk-users] GXP2000, Linksys RV082 Firewall / NAT, Registrations

[lists at infoway.net]

Did I forget to mention I had STUN enabled? :)

Well, that did it. Your suggestion worked perfectly.

Does anyone know what a reasonable NAT Keep-Alive to use, if you don't
have access to their firewall/router configuration?

Thanks,
Daniel

Do you have STUN Enabled?   I had similar when I had STUN turned on.  I
found it better to turn off stun and place in sip.conf   "nat=route".
Also use "NAT Keep-Alive" on the ATA that is < "NAT Timeout" on the Router.

Good Luck,
