cucm 8.5 bulk edit extension numbers.

Amit Singh2000

Hi guys

We have a customer who is moving from 4 digit extension to a 6 digit plan. I have phones registered to call manager with 4 digit number already.

What is the best way to update the extension numbers to adhere new dial plan.

Can anyone share the ideas please.

I was trying to export the config. Update it. And import it. But what I have noticed is that in the export config directory number option doesn't even exists.

Thanks in advance.

Hi Aaron,

This does not work for 10.5. do you have an updates version? is this utility available commercially / paid version that supports 10.5?


I can certainly make something available for you on that basis if you like.

Hi everybody,

Did already a version of this tool AXL to version 11.5? I´m trying the upload in this forum but I get the error: ERROR: Directory Number not found

I would appreciated if there a tool for this version of CUCM.

Hi Aaron,


First of all thank you for the tool. I am wondering whether you have an update for CUCM 10.5 or later. It says Directory Number not found.


Thank you in advanced,


Hi Aaron,

I know a bit of Perl. I would like to write 2 scripts in that language. One that takes an input csv file (like in your Java program but the values will be old partition, DN, new partition) and updates the partition on a DN to a new partition. The second script takes an input csv file with DNs, it finds all devices that have that DN as a line and reboots them. I am okay with running such scripts from a cli environment. Do you know if Perl can achieve these request? Two, what documentation can you point me to so that I can build such scripts. 

Your help is greatly appreciated.
