IP address call
If the AT-VP504E FXO is not configured to register with a gatekeeper,
you can reach one of the AT-VP504E FXO ports by dialing its IP
address and the corresponding E.164 alias. This requires a LAN H.323
endpoint that allows to call both an IP address and an E.164 alias.
What is a Dialing
Rule?
When using the AT-VP504E FXO FXO ports to make calls, these calls
follow the dialing rule you have defined (see
“Configuring Incoming and
Outgoing Calls Parameters” on page 41
for more details).
A dialing rule is a logic used to parse the digits (DTMF) received from
a telephone company line (FXO port). It helps to determine if an IP
address or an E.164 alias is complete.
General Dialing
Rules
The rules are applied according to a specific priority
order. They are presented in this priority order.
The dialing rules are configurable from the Configuration
web page. Each FXO port can have its own dialing rules.
The one digit speed dial cannot be equal to the end of
dialing character.
When the PSTN user dials a sequence that is not
recognized as an E.164 alias or as the IP address prefix,
an error tone is played to the PSTN user.
If the PSTN user dials an invalid IP address, for example

is not configured to register with a gatekeeper.
