I am using Odoo 15 EE and I want to test VoIP.

I have installed Asterix in my local network and I have created two extensions using FreePBX 15.0.16.75 interface. I tested making calls from one extension to another using Zoiper softphones and the calls were correct. This way I could validate Asterix server is correct.

Moving to Odoo. I have v15 EE running locally (docker environment) and I added extension numbers in two employees and added the VoIP integration settings in General settings like this:

PBX Server IP: -> local IP address like 192.168.1.127

WebSocket: ws://

VoIP Environment: Production

When I save with the debugg mode activated, I see in the browser console

Connecting to WebSocket ws://192.168.1.127

If I remove the "ws" from the websocket url, and let only the IP address I dont have any error.
BUT, when I click in the phone icon in Odoo to initiate a call it says: The server configuration could be wrong. Please check your configuration. Any help, please?The server configuration could be wrong. Please check your configuration.
