Teams common phones limit dialing

New Contributor

I work in a college environment with emergency phones in the halls. We are converting to Teams phones and want to configure these phones to either only dial 911 or a limited set of numbers. We don't want students to just call anybody from these phones which are basically not monitored.

You haven't mentioned if this is Direct Routing. Assuming it is, you need to create a Voice Routing policy for this purpose, then define a restricted PSTN Usage to specify the exact digit patterns you want to allow. TIP Use the really cool tool from James Cussen, you can find it at

Thanks for your reply. We are not using direct routing. I am attempting to set up dial plans that will forward all 7 or 10 digit calls to our operator or security.
