Hosted PBX iptables rules
-
Just something I ran across today setting up some stuff in the hosted PBX one of my clients has from NTG.
In order to setup OpenCNAM as a source for caller ID lookups, I needed to access raw.github.com. The current iptables configuration prevented that.
I stopped iptables, ran the scripts, then restarted iptables.
After that, I added OpenCNAM as a the lookup source form the routes and everything worked.Instructions: https://www.opencnam.com/docs/v2/pbx
