Smart DID
】
:
There’s a default Smart DID rule, which enables all outbound calls being monitored by Smart
DID feature. If the call is not answered by the called party then the called number will be stored
into Asterisk database with the extension number which made this call. While the called party
calling back the IP PBX system can automatically direct this call to the extension number
directly.
If you don’t want all outbound calls being monitored by Smart DID, you can modify the existing
rule or click “New Smart DID Rule” to add you custom rule/rules. An example as below:
Item Explanation
Pattern Defines the number format which would be dialed.
Strip Remove some digits from the front of the dialed number.
Prepend Prepend some digits in front of the dialed number after
manipulated by the “Strip” option.
The numbers to be dialed will start with prefix 17951 and if they call back, the expected
numbers will have +886 in front of them instead of the 5-digit prefix 17951. In such a situation,
the outbound and inbound numbers are not the same, you’ll need the “Strip” and “Prepend”
options to manipulate the dialed numbers to make sure it can match the “same” number when
it calls back. If the numbers to be called and the numbers to be received are the same, then
you don’t have to configure these 2 options. Or you can configure only one of these 2 options,
