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 +86 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.Alternatively, you can configure only one of these 2 options,it
will all dependon your actual requirements.
For example, the extension user 401 wishesto call 85337096, and the carrier requires a prefix
17951 to ensurethe rate is much cheaper. The user willdial 1795185337096 to place this call. If
the called party misses this call then theIPPBX system will store this 8685337096 with
extension number 401 into its database. Later on, if the called party tries to call back, the IPPBX
system gets +8685337096 as the caller ID and matches this from its database, once successfully
matched, this call will be automatically directed to extension 401.
Notice
:
1. The records forSmart DID functionality in the system database will be erased every day at midnight. Thismeans
this is a dynamic effective feature and is only designed to handle callbacks made within the same day as the
original call.
2. In the “
Pattern
”field, patterns can be used in the same way as the patterns used to manipulate dialed number
in the dial rules. Please refer to
chapter 3.2.1
.
3. Due to the mechanism of how Asterisk works, at this time Smart DID only works with VoIP trunks anddoes not
work with FXO or GSM/ WCDMA trunks.
4.16CallBack
Callback is to allow a company employee who needs to make a call from their personal phone to
call the IPPBX, the IPPBX calls them back and the cost of any future outbound calls are at the
companies expense.
