PBX setup: Issues with outbound Caller ID

In the earlier part of the week I discovered that when I make a call from my FreePBX/Asterisk setup that I’m putting together for my business, the business name I set up on the outbound Caller ID/Caller Name (CID/CNAM) wasn’t appearing on my cell phone.

After a support ticket with my SIP provider and a ridiculous amount of testing, we determined it’s my cell phone carrier that’s at fault, not my PBX nor my SIP provider. The provider is passing along both the CID and CNAM to the cell phone carrier, but the carrier for some reason is not displaying the CNAM when it completes the call.

I also discovered that if I set up a spurious CID such as 1-204-555-0012, the cell phone provider actually displays the CNAM. So now I have in my phone logs a call from HRH ELIZABTH II 😊
