Hi there, kinda new this but had done some work. I managed to setup the pbx but not sure about the firewall. Not my area.
At this moment I have a trunk with and inbound route. I have 2 extension and nothing else setup.
The Inbound route is pointed to the extension (100) and the extension has the Follow Me on and directed directly to my cell phone. There is no hard nor soft phone attached to the extension.
Basically I’m testing and have an external number pointed to my cell number through the PBX.
Here is what I don’t get.
Just restarted the PBX after a couple of hours off.
No call made nor received.
The CRD reports shows activity and I can’t understand why. Can anyone illuminate me on this?
Eager to learn,
This is the result shown when I click the entry id at the crd report. and BTW this PBX is hosted in a hosting company (Vultr), a friend of mine is running a PBX for a company and works great.
The hosting account has no firewall at all, so the IP is exposed to the Internet.
There are two firewall components. The first is the “Integrated” firewall. That’s the one that sets up your basic trusted and untrusted networks, opens ports, etc.
The second it the “Adaptive” firewall. That’s the one that accepts calls from SIP/PJSIP/IAX2 phones and watches to see if they succeed. If they fail and the performance thresholds for “blocking” are reached, the callers are blocked. If you allow anonymous and guest callers, though, the calls succeed. This means that the only heuristic the Adaptive firewall has (failure) is not met and the firewall does as instructed and ignores the call.
