There is no support for doing so. You would need to modify the outbound registration code.

hmm? how can i do that in asterisk? can you help me on the way ?

There is no guide or anything. It’s modifying the underlying code to add support for such a thing.

Oh ok, too bad…
Any idea bif it’s possible with FreePBX?

FreePBX uses Asterisk underneath, it would also not have the functionality you’ve asked for.

Is that possible for a trunk?

Can you add headers to a REGISTER?

Yeah, verry interested in this too

No, you can’t use PJSIP_HEADER To add headers to a REGISTER. It only adds to outgoing INVITE requests.

ups did not notice ti was for REGISTER
