Alex -
Check out the presense settings. Make sure both profiles are using the same DB:

Alex,
Does FS *have* to be behind a NAT? Are you doing a straight 1:1 from public to private (FS side)? What kind of router/firewall are you using on the FS side and endpoint sides? You'll will probably want to lower the endpoint registration times from the normal default of 1 hour to 180 seconds (3 minutes) or even lower depending on router/firewall. You may also want to turn on keep-alive packets to keep the data flowing in/out. What you are running into is either one or both sides are closing off 5060/udp early, FS is marking the registration as dead.
Anthony,
No, it's definitely not that - the registration is alive and well. The issue is that FS sees that the user is not registered on the internal sip profile and doesn't check the doublenat profile.
The router/firewall is iptables (shorewall) and I'm doing a DNAT of the relevant ports to the FS box.
What I have found is that I can specify the dialstring for the external users in the directory entries, eg:
<param name="dial-string" value="{sip_invite_domain=${domain_name},presence_id=${dialed_user}@${dialed_domain}}${sofia_contact(doublenat/${dialed_user}@${dialed_domain})}"/>
Best thing to do is to place FS in a DMZ or install a public facing SBC to take the registrations and forward them on to FS internally.
Yes, it would probably be better that way, but this is really mostly for internal use.
Cheers

Hi all,
I have set up a new profile for phones behind NAT connecting to an FS box behind NAT. Calls in from a NAT'ed phone works fine, however calls out to one fail with USER_NOT_REGISTERED. All the phones are set up in /opt/freeswitch/conf/directory/default/<sip id>.
I have added the following in the new profile config hoping it would resolve the issue but it does not:
<param name="challenge-realm" value="$${domain}"/> <param name="force-subscription-domain" value="$${domain}"/> <param name="force-register-domain" value="$${domain}"/> <param name="force-register-db-domain" value="$${domain}"/>
Any clues?
Thanks
Alex
