[Freeswitch-users] Created new profile for double-natted phones, calling these fails with USER_NOT_REGISTERED

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
