This tool will check if your network allows connections to our PBX server on all the required ports:
How this works: We'll test specific UDP ports (5080, 5081, 4399, and selected ports from 10000-20000 range, plus 19302) by making SIP calls with custom ConnectRTP headers. Each call tests both connection success and audio reception from the PBX server. We'll also check TCP connectivity using resource loading tests.
Important: This test requires permission to use your microphone temporarily. This is only for testing network connectivity - no audio will be recorded or stored.
This section shows the progress of testing each UDP port with SIP calls. Each port will be tested individually with a ConnectRTP header to verify both call establishment and audio reception.
