Title: Internal Dialing Plan
Post by: pakman on June 13, 2018, 04:44:58 PM
Currently, we have all DIDs and the last 4 digits of everyone's number is their internal ext. Currently, you dial 4 digits to get anyone in the company. As we continue to grow and acquire more locations we will run into DIDs that overlap. I'm wondering what other folks have done that have come up against this situation?

 I'm thinking we change over to a 10 digit dial plan for the entire company except maybe dial the last 4 if that person is local to your building. Not sure that's even possible with Mitel.

Thanks,

If the new locations are being setup from scratch, you make sure your carrier provides you with number ranges that don't conflict in the last 4 digits with your existing ones.
If the new locations are already setup you could change their number ranges and extensions so there is no conflict. Otherwise, you could add the new locations as 5-digit internal extensions, assuming of course that those numbers don't conflict with existing internal extensions (eg, if you current have extensions in the range 4600-4699, then you can't have 46500-46599 as a new range of internal extensions, unless you stop using 4650-4659).
If it's all too hard, you have to stop associating your in-dial ranges with internal extensions as matching numbers. There are downsides to doing this, so plan it properly.
