Summary:                    Asterisk Realtime not resoving host names
Description: 
Using asterisk Realtime I have noticed that incoming calls will not work
unless you change the HOST field from domain name to a physical IP
address.

If a domain name is specified for host the bellow NOTICE is seen on
asterisk
 NOTICE[3008] chan_sip.c: Call from '' to extension '13864345565' rejected
because extension not found.

We tested this many times and if a domain name is specified for HOST then
98%
of the incoming calls gets rejects with the above NOTICE.

Okay, so it's fairly obvious why this isn't working for you:  the SIP
client isn't sending the hostname; it's sending the IP address, so Asterisk
naturally tries to match the IP address in the URI that it sends.

If your client sent the hostname, then you could use the hostname in the
realtime database.  However, since it didn't, Asterisk has no way of
knowing that that's the host that you wanted.

No, we do not do reverse DNS (PTR lookup) in the middle of a SIP dialog,
as that introduces a great deal of latency into the connection.
