How to obtain DID from extension ?

[loueloui]

Hello All,

We have a G3r at a site which is unfortunately not well documented. What is the easiest way to find the DID number from the extension through ASA? Thank you in advance.

To the best of my knowledge, you can't locate the DID from the extension, but you can certainly find the extension through the DID however.

You'll need to look through your Incoming Call Handling Treatment tables and locate the called number / insert that corresponds to the extension you're looking for.

Command: display inc-call-handling-trmt trunk #

Where # is the identification of the trunk that takes incoming calls.

DID number ranges are not programmed as such in the Definity / CM.

Dialed Number Identification Service (DNIS)
Direct Inward Dial (DID)
Mapping of digits and length is controlled by the provider.

Call your provider and ask what your DID ranges and all numbers routed from the
public network to your trunk circuits.

Besides DID, DNIS digits for other numbers like 800, 877 is another thing to
ask for.

Called number 800-222-1234 - DNIS 3000, 2221234, 1234 are all possible, it's not
always the last 4 digits. Many public numbers can be routed to your trunks and
the provider can send DNIS digits for these to the trunk when seized. These
digits may or may not match your PBX dialplan.

Ordering DNIS service and planning is important when ordering new numbers or
when switching providers. Not matching DNIS digits to work with your PBX's
dialplan can be a housekeeping nightmare, not to mention, the difficulty to
troubleshoot call flow.

A great teacher, does not provide answers, but methods to teach others "How and where to find the answers"
