This is ALL the information I have from our provider:
Our phone number is: 214-329-4838
That phone number is bound to our IP address: 188.8.131.52
Our Providers IP address is: 184.108.40.206
There is no registration necessary. I will send an invite and 220.127.116.11 just needs to accept it from 18.104.22.168.
Currently, this is how I have the SIP trunk setup:
Anyway, for a bit I had there I had outgoing calls working. However, 2 way communication didn’t work. I could be heard but not the other way around.
The provider isn’t being much help. Any ideas?
