Hello Srigo, yes, a gateway sending out a REGISTER. And I want to add headers to it before it’s send out. I DO NOT mean adding headers to an REGISTER response send to a local extension. To be precise I wanted to add “Require” and “Proxy-Require” headers. But I failed on adding completely new headers.

If yes, I'm not sure you can do it.

But the documentation refers to the dialing plan. I tried to add headers to an outgoing REGISTER but failed. Because the documentation refers to the dialplan and changing headers for existing calls, I am not sure if adding headers to a REGISTER request is possible or not. Can anyone please tell me if it is possible or not and if yes, how to formulate the correct “<action application=”set” …>” and “<condition>” sections in the configuration. Thanks in advance for all answers.
