Failed to Receive Inbound Calls through Analog Trunk

Symptom

I can make outbound calls but cannot receive inbound calls through my analog trunk.

Solution

In this case, please check if the analog trunk has been selected in Inbound Routes.

1. If this trunk hasn’t been selected, please move it to the “Selected” box directly or add a new inbound route for it.
2. If this trunk has been selected in the right inbound route, the problem might be caused by the mismatch of signaling. Please select “Trunk”->”Analog trunk” and change the settings of “Caller ID Start” and “Caller ID Signaling”. You might refer this guide to configure the correct Caller ID detection. Why There is No Caller ID for Analog Line?
