I’ve had no issues with my PBX server until recently, I’ve been unable to dial out to both extensions and outbound numbers. I verified my account secrets on all my phones and verified iptables/firewall isn’t blocking my office ip. My PBX is hosted on a VM on my server in Texas.
When attempting to dial out/intercom/etc, there will be no audio and after aprox 15 seconds, “No Response” is displayed on the phone. I checked the logs and the only thing I could find is in the requests from the phone to PBX, its showed the local/lan IP of the phone on my office network (192.168.1.151). The phones are all showing registered in PBX so I know they are able to get through the network. So I’m unsure if this is at fault.
I redacted IP’s but for clarity “FreePBXServerIP” is my server in texas that PBX is hosted on, OFFICEIP is the public IP for my office, PHONENUMBER is an external phone number I used to test an outbound call.
