Mitel MiVoice Business/MCD/3300 / Re: Unknown on Calls Forwarded to Cell Phone

It's a PRI trunk. We are not using a softphone over LTE. We only have the single Mitel 3300 PBX node.

I should note that our cell phones are set up as phantom devices with their own phantom extension with the cell number being plugged into the External Hot Desking Number field for that device. For example, a desk phone could be 7889 and the cell phone device would be set to ext 8889. Both devices (7889 and 8889) are then configured as a personal ring group.  So if somebody calls 7889, it automatically rings 8889 at the same time. However, since it's only passing 4 digits to the cell phone (i.e. going out through the PSTN) it shows up as unknown on a cell phone's caller ID.

From incredibly similar reported issues its often mentioned that the numbering plan on the PBX needs be updated from unknown to ISDN, but I do not believe that is an option on our particular system unless we were using a E1 embedded PRI.

Let me know if there is any other information I can provide.

That is correct. Calls do reach the cell phone over the PSTN, but without any number on the caller ID, so it just reports unknown. I'm wondering why the 4 digit extension isn't being re-written with the full set of digits via our existing CPN substitution rules . Or maybe that has nothing to do with this particular issue.

And hopefully I was clear in my original description about incoming calls ringing both the cell phone and internal VoIP phone at the same time.

I know this has come up many times before since cell phones made the switch to VoLTE, but I'm still struggling to find the solution for our own Mitel 3300 PBX (running Release Level 7.2 SP1 PR1, Active Software Load: 13.2.1.27). Before VoLTE was enabled, extensions from within our company were forwarded to our cell phones (which as a part of a personal ring group) and would show up as a 4 digit extension. However, with VoLTE enabled, they now show up as unknown on the caller ID.

Where should I start looking to try and correct this so that either the full # is passed through or even just the 4 digit extension again?  Or what other information can I provide to help narrow down the scope of this question a bit?

Thank you.
