Calls Without a SIP Server
If the AT-VP504E FXS is not configured to register with a SIP Server
you can make SCN to IP network calls by dialing an IP address.

the help of a SIP Server by entering its IP address. If you are dialing
the IP address of an AT-VP504E FXS (which has four ports), by
default, you will reach the telephone/fax connected to Port 1 of this 4
ports terminal.
