After typing a lengthy post, I got an error saying I didn't have enough 'karma' to post a link, and my post was gone. So here is a shortened version without the links:

I am trying to set up an VoIP integration with Ringover:

But when I try to call a number using the Odoo dialer, I get brief dial tone, then an error message saying:

"Call rejected (reason: 'Bad Request : Please use a correct gateway")"

Where can I find the Gateway settings?

Thanks,
Shane.
