Making Calls
When making calls, the digits (DTMF) you dial are checked against a
dialing rule. A dialing rule is a logic used to parse the digits received from
a line (FXS port). It helps to determine if an E.164 alias or an IP address is
being dialed or if an IP address is complete.
Dialing rules can be set for the following items:
When you dial a sequence that is not recognized as an E.164 alias or as the
IP address prefix, an error tone is played. If you dial an invalid IP address,
for example “192.168.2488”, an error tone is played as well.
The way you must dial digits is directly influenced by how your network
administrator has set up the dialing rules. Allied Telesyn strongly suggests
that you check with your network administrator before attempting to make
calls and verify the dialing rules he/she has implemented.
