Going to 3 digit extension

[unclejemima]

I apologize if I've asked this in the past...

We are currently using 4 digit extensions for our phones.  Our offices have 3 digit room numbers, and we used to have offices with 2 phones in it.

Example, RM112 phone #1 would be 1121 and phone number 2 would be 1122.

Easy somewhat, but users have been complaining on going back to 3 digit extensions.

From some testing I've done, it appears I can change an extension and it will update other area's of the DB where the record was used...is this correct?

Can I have 3 and 4 digit extensions?  Example, 112 and IF there is a second phone 1122.

Thanks!

Your extension numbers can be between 1 and 5 digits.

However, the example you used will not work. If you use 112, then 112x is not available.

Thanks.  So if I go 3 digit, I have to have all 3 digit and so on.

Works for me.

You can have a mix of numbers between 1 and 5 digits, the system doesn't care. You just need to be careful with your numbering plan.

DND ON is saying that if you have an ext 123 you can't also have a 1234 (or 123 followed by anything}.  But you certainly have a 1245 or any other 4 digits, as long as they don't share the same first three digits of any 3 digit number.
