Bulk to change the USER ID field for Anonymous phones

[Joel Benicio Contreras Cid]

Hello everyone. I need to assign a "user id" to the phones since they are all assigned as Anonymous. I see that the option is to do an export all, change the USER ID field of the existing users and do an Insert Phones All Details (Since there are multiple sites and multiple phone models, there are more than 2000 phones). I don't want to do this yet since the risk is great if I make a mistake. Is there any other safer way that does not involve other fields? My CUCM is 12.5.1.17900-64

Thanks in advance

Not natively in CM. Bulk update is the option at hand for this. The best way is to start working on the format of the update file for one or a couple of devices and then when you have that locked down you’ll do the update on all your devices. The option you have is to use the AXL API if you’re proficient in programming and write a custom update application that only touches that specific field on each device.

There’s a tool from Cisco called Device Assignment Tool (DAT) that can accomplish this, and it’s available for download. However, it doesn’t work with version 14. If you’re using version 12.5, it should work as far as I recall.

You could download the application from the below Link.

You can find the admin guide from the below.
