I have a small business with a PBX 17 server. It is located behind CGNAT (Starlink) without the capability to receive incoming connections. I use a VoIP provider that handles all incoming and outgoing traffic. Lately, I travel away from my site and configured my cellphone number into my ring group. Now, I receive incoming calls as expected. BUT when I try to call into my PBX the call goes straight to voice mail menu and I can no longer get to the PBX extensions.
In my Ring Group I added my cellphone number to the list “XXXXXXXXXX#” It would not work without the “#.”
a PBX behind a CGNAT has it’s issues … did you ever think about a VPN provider which gives you a fixed IP? You’d then be able to use your FreePBX easily with VoIP phone apps. Groundwire works perfectly for me to have my FPBX extension right in my pocket.
I’ve seen it happen where the ring group tries to ring the remote cell phone but if the phone is in use(ex. you’re using it to call into your PBX) or if the remote cell phone has no service, it will not try the other extensions. The cost isn’t too bad, I’d maybe look into getting Sangoma Talk for your one extension to go away from using find me/follow me type setups. Then you could call out from your PBX’s number rather than with your cell phone.
If I am understanding this correctly, the issue only occurs when your cell phone calls in to your business?
If thats the case duplicate your inbound route(s)
Set the caller id to your cell number
set CID priority rule to yes
then make a cloned ring group of the original without your cell number in it, you should get through just fine, and set the new ring group as the destination to the cid enforced route.
