Number to Username Translation, Is it possible?

Hello, pardon me for the stupid question. Been tinkering with how I can work with extension dialing in msteams, and found out I can utilize tenant dialplan to tranlsate 3-4 digits to DID. The pr...

godril I've just performed a little science experiment. I ran the following PowerShell command for a user in our tenant which does not have a PSTN assigned:
Set-CsUser -Identity userwithnopstn@example.com -OnPremLineURI tel:1234
I then dialed "1234" from Teams and the call was successfully routed to the user. So yes, it does seem it should be possible.

Hi,

there is no number to username translation. Users get a number with phone system to be reachable from the PSTN (calling plan and direct routing). If your users try to reach each other internally they should use the search or contact list to reach them. This would initiate a conversation based on the username (UPN).
A concept when multiple users share the same number externally and have an own internal extension is not available in Teams.

Regards,

Paul

Hi paul-lange

Thank you for replying.

You are absolutely right. The question arose because I am trying to integrate legacy pbx system with msteams phone system direct routing. It is not a matter of technical but merely because of old habits die hard from the seniors. I am wondering if there is a way to workaround or if there is best approach for the extensions calling between the systems before convincing them to purchase more DIDs.

Ok. Understood.
If I understand you correctly you are using Calling Plan and Direct Routing at the same time. Do you plan to have Direct Routing for users or just to integrate the PBX users?
What you can test is that you build a dialplan with normalization rules that normalize the extension range of the PBX to e.164 and Route it via the SBC to your PBX. To my knowledge, this should also work for users having a calling plan.
The other way around (PBX User -> Calling Plan User) would then also be routed via the SBC.

Edit:
The attached picture shows nearly what you are trying to accomplish.

  Hi paul-lange
  
  thank you for replying on the weekend.
  
  I actually only do direct routing for the users besides integrating the legacy PBX. I think this idea is the same path with what Ryan Steele mentioned. Will surely try this too. Thank you thank you thank you.
