[Freeswitch-users] SIP external profile - Error looking up host name

[Anton VG]

Looks like a nasty bug.
Until I have put a gateway IP in realm sip_profiles/external - FS
gives a DNS error and will not register
Freeswitch  - fresh GIT

At the same time I can resolve a dns record via nslookup
(note real domain name was replaced by name.tld and real IP by X.X.X.)
