Phone Number Translation
This table can be used to translate phone numbers into IP addresses or Hostnames. If an
attached device dials one of the specified telephone numbers, the corresponding IP address
and port are used to make the TCP connection. Note that all non-numeric characters except
the “,” (comma) in the phone number are ignored.
Terminal ports detect the dialed numbers from the DTMF tones generated by the attached
device. Serial ports, when modem emulation is enabled, detect the phone number from
ATD commands. Although the IP address of the remote host can be embedded directly into
the ATD command, certain devices can't always be easily configured to do this.
The Default Translation entry is used if the dialed phone number is not found in the list. If
there is no default entry, then the call will be routed to the modem (dial-backup) port, if
present.
The dial backup port will also be used if the host associated with a given phone number is
not available. In this case, by default, the modem will dial the same number that came in the
port. However, you may specify a Dialout Phone Number to be used on dial backup
instead.
The phone number table has a number of features to ease initial configuration. When an
attached device dials a number that is not in the table, the gateway creates a dummy entry in
the table. This entry will consist of just the phone number. Until you fill in the remainder of
the entry (IP Address/Hostname and Port) this entry will not be used.
