Migrate from 3 digit to 4 Digit extensions

[wbarren]

We are in the process of migrating from 3 Digit to 4 Digit Extensions. We are running call manager 5.x is there a way to use bulk administration to update the extensions?

Here's one way to do this:

1. Use the BAT export utility to export all details of your phones to a CSV file.

2. Modify the extensions in the CSV.

3. Delete all existing phones.

4. Use BAT to import the updated CSV file.

Be sure to make a copy of the original exported CSV file before modifying. It would also be a good idea to test with a couple of phones before updating all devices.

Hope this helps.
