3CX v14 - Extension Length

[tiagomoreira]

Hi,

We have a 3CX system v14 with extensions with 3 digits. We need to change now to 4 digits.

Do we have to reinstall the whole system again and reconfigure from scratch? Is there any way to edit the config file or something like that?

Thanks in advance!

I am quite sure the answer is yes, you will need to reconfigure completely.
