Hello I am new to VoIP and SIP so I thought I would try to learn by doing. Unfortunately I’m ripping my hair out with trying to get this to work. I’ve looked at the forums from my sip provider(Twilio), my router(Unifi USG), and FreePBX I have tried absolutely everything I could find.
On internal calls there is no audio at all.
On outbound calls the soft phone(X-Lite) can hear the PSTN but the PSTN can’t here the soft phone. And on top of that the calls end after 30 seconds, my sip provider(Twilio) says that the “caller”(PBX or soft phone) is ending the call.
Any help is greatly appreciated and if you need more information please ask!
