Incoming PSTN call with FXO gateway

max69hk

I have a Grandstream 4108 FXO Gateway connected to Axon and using X-Lite on my computer. I have no problem making outbound call to PSTN, but when I call from the PSTN, Axon prompted that "Incoming call failed" and "Unable to find any lines with the ID "101" or extensions with the ID "unkonwn"".

But I have registered my x-Lite with the ID 101. Why Axon still saying cannot find the extension?

Is there anything I missed for the configuration?

Or is there any dial plan for incoming?
