This document covers the configuration procedure to implement short dial numbers in Cisco Unified Communications Manager 8.x (CUCM) on a per location basis.
How call routing works with Short dials?
When a user enters a short dial number, it is modified by the appropriate translation pattern and then routed normally. Calling search spaces and, to a lesser extent, partitions play a vital role in routing the call properly.
We will set up basic short dials on a per location basis.We will need a location-specific partition for the location for which we are implementing short dials. In this case we use PT-SFO-DialPlan.
Note: Below configuration is tested on Cisco Unified Communications Manager 8.x/9.x release.
To implement short dials for a location, perform the following:
Step 1. Add the short dials partition to the calling search space of the device for the relevant location
Go To Call Routing > Class of Control > Calling Search Space:
Step 2. Create and save a translation pattern for the short dial in an appropriate partition
Go To > Call Routing > Translation Pattern:
Step 3. Fill in Translation Pattern and Partition as appropriate. Here we use 2200 and PT-SFO-DIALPLAN, respectively.
Step 4. Calling Search Space. Here, we apply a device calling search space appropriate to the location, CSS_HQ_SHD.
Step 5 Finally under the Called Party Transformation section, we change the Called Party Transform Mask to the Final number as 4552
How it works?
When a call matches the translation pattern 2200, the called number is translated as per our rule to 4552, and the call continues to be routed normally.
I have received several trouble tickets in the past 2 week with basically TWO different problems:1. When creating a new Session in CANVAS with the Education Connector, faculty is getting "We are having trouble communicating with Webex at this time"and2. I...
Good afternoon, all!I'm retiring a server that, among other things, is the SFTP target for my customer's UCM Disaster Recovery System. This is a Debian 10 server with ProFTPD as the SFTP server. I can access this using WinSCP as a client and use any of th...
Hi all, have a question that has me stumped (not terribly hard to do). I'm setting up dial-peers on my CUBE to handle the call leg from the gateway to CUCM. I have a default .T dial-peer setup that seems to work. When I...
So I have a SIP trunk created to connect my CUCM environment to a Poly environment. I am using a 10 digit extension, which is a DID number, on the Poly endpoints and have created some route points in CUCM. I am pointing the route points to the...
