Hi all,

In our location extension numbers are starts with 7XXX and 6XXX and now we need to change the extension numbers to 8XXX.

So i need to write any route pattern. I also cmae to know that Their is  no route pattern for 7XXX and 6XXX. What is impact of translation pattern here.

Changing extension is usually a nightmare. I suggest the following:

- Complete the prep work for the new range including route patterns and digit manipulation 

- Configure test phones with the new range and make test calls inbound and outbound to match your requirements

- Export the phone/DNs settings using bulk administration

- Modifying the DN numbers in the exported bulk to be in the range 8xxx

- Schedule a downtime, delete all phones with their DNs and import the new file
