Short-cut Dialing in CUCM

[Michael Dougherty]

Greetings,

Is there a way to assign full 10 digit to each user but allow them to dial only the last 4 internally? I looked into the local route groups, however, it appears to applicable to routing calls to outside peers or destinations. The end-user currently has 4 digit dial between handsets and want to make the transition simple.

Running CUCM 12.1

I appreciate any thoughts or suggestions.

Two different possibilities:

Configure 4-digit Enterprise Alternate Numbers on the DNs. If the 4-digit dialing patterns are unique across the cluster then configure a system-wide partition for the EAN. If the 4-digit dialing patterns are site-specific, configure a site-specific partition.

Translation patterns can be used to take 4-digit dialed numbers and turn them into 10-digits. The caveat to this is that the 4-digit extensions would have to be summarize-able, meaning a set of 4-digit extensions such as 4XXX would have to have the same NPA-NXX prefix. If so, then the translation pattern would be:

• Matched Pattern: 4XXX
• Partition: One that is available to the phones dialing this pattern
• Called Party Transform > Prefix (Outgoing Calls): 222333
• (Or, alternately, a Transform Mask of 222333XXXX)

However, if some of the 4XXX would have one NPA-NXX prefix and others would have a different NPA-NXX then this is more difficult.

Let us know if this isn't clear or if you need additional information.

Hello Maren,

I appreciate the response and tried the EAN on a few test phones and positive results. I also tried the translation patter, however, that did not work. Is it just configuring the pattern as indicated below or is there something else that is also required?

If the EAN works, that is the way to go because it is easy and consistent.

As for translation patterns, double-check that you are prefixing/transforming the section "Called Party" which will modify the dialed number, and not the "Calling Party" which will modify the caller ID. That is a rookie mistake everyone makes at first.

If you did configure the translation pattern correctly, then the issue is probably related to partition/calling search space. I don't know how familiar you are with those and I don't want to assume. But if you don't have a solid grasp on PT/CSS I encourage you to read up on it. I teach Cisco Unified Communications for a living, and in my opinion having a solid understanding of how PT/CSS works is the single most important concept in understanding how CUCM works overall.

Thank you for your advice, I am going to stick with the EAN per your recommendation.
