Unable to Dial In On Grandstream

FreePBX Endpoints
1

Hello, I acquired a Grandstream gxw4104 and am having problems getting it to pass a call to my PBX. I can dial out without any problems but inbound always tells me “No Matching Endpoint” and then “Failed to Authenticate” in the CLI.

I followed the instructions at Sangoma Documentation but it doesn’t mention the inbound trunk settings. I have left them blank and filled them in and it doesn’t seem to make any difference.

I do have an inbound and outbound route and can dial 7777 and have it route properly so I believe my inbounds are correct. My logs are as follows (number changed obviously):

The wiki article refers to a chan_sip trunk. With default settings in your PBX, Bind Port for chan_sip is 5160, so in your Unconditional Call Forward settings in the GXW you should change
Sip Destination Port: ch1-4:5060
to
Sip Destination Port: ch1-4:5160

If no luck, post another log with the new setting.

That seems to have done the trick. Thank you very much for the help!
