PBX Connection Check is a small tool for verifying the remote reachability of a Voice@work phone system.
With on-premise phone systems, it can happen that after network changes the PBX is no longer reachable from the outside. The software was created to let technicians quickly check that connectivity was still working correctly.
It was the first piece of software I built from scratch for Voice@work.
Running the check
The interface is deliberately simple: the technician fills in one or more fields and starts the check.
Tests are available for SSH, HTTP/HTTPS, and TCP/UDP connections. This makes it possible to verify administrative access, the web interface, and the voice flows used by softphones.
By entering the SSH port, usually 22, the system checks whether SSH access to the phone system is still available and working.
After loading, the tool shows the outcome of the checks it performed.
