■ Voice Entity view
Description This command only applies to the configuration of POTS voice entity. And the
dial-prefix command only applies to FXO and analog E&M interface. Whether to
send a second stage dialing tone is determined by the configuration of the PBX
connected to the router.
When a router with which a voice function is configured receives a voice call, it makes
a comparison between the number configured in the match-template of its own
POTS voice entity and the number received, and selects one POTS voice entity to
continue the call processing.
If send-number is set to its default value (truncate), the router will remove from the
called number the string that matches the
match-template beginning from the
left. If the
dial-prefix command is configured, the prefix will be added in front of
the rest of the called number. The router will initiate a call according to the new
number string. For example, supposing that the called number is 0102222, the called
number template of the voice entity that is configured by
match-template is
010…., and the dial prefix is 0, then “010” that accurately matches the template will
be removed, and the rest part “2222” will be added a prefix “0”. The router initiates
a call to the new number 02222.
