I want to use diversion, tell me what I need to enter in the diversion domain in the gateway for everything to work?
You have to enter diversion domain there.
Can you be more specific about what this means?
Should I enter my IP there or not the IP in general?
Diversion uri contains domain. You have to enter it there.
It is hard to say what exactly you expect to send. Also words “use diversion” are not explaining what exactly you trying to achieve.
I have a server where I receive a call, substitute this header in the form of the number that was called and send it to Yeti, after which I need this header to go to the supplier.
But from the dumps I see that Yeti accepts this header, but then does not send it to the supplier
