Configuration How-to’s
For example, to give local users whose extension numbers start with
56
the capability to
make outgoing calls through dialing technical prefix
0
, configure source and destination
number transformation as shown in the table below:
Match
Pattern
Result
Source ^56.*
^(56.*)
$1
Destination ^0.*
^0(.*) $1
According to this rule prefix 0 will be cut off from the destination number because the
internal prefix used in the system is of no relevance to the gateway sending calls outside the
system.
The syntax of regular expressions appearing in the field
is identical to that of
regular expressions entered in the field
.
The table below contains a list of regular expression constructs applicable in configuring the
