In-Depth Information
necessary to allow inbound calls to match the extensions of the local phones. This command also ensures that a full E.164 address is
sent as the ANI in outbound calls.
The dialplan-pattern command causes the SRST router to create an additional virtual dial peer for local extensions corresponding to
the pattern specified in the command. In this way, this command can be used to map the DNIS sent by the PSTN to a local extension.
So, for example, the SRST router might receive a call with the DNIS 5055512345, but the local extensions range might, for example,
be from 340 to 350, so no match occurs and the call fails. But, if the dialplan pattern 1 5055512... extension-length 3 command is
specified, the SRST router is able to match the DNIS 5055512345 with a local virtual dial for 5055512345 (the additional virtual dial
peer created for extension 345), and the call succeeds.
