Hello.  
I want to add User-To-User value to sip header when making a call.

Please guide me on how to set the User-To-User value and configure the trunk.

We just had to do something similar. You’ll want to use these in your scenario before that user to user handoff is made.

$(item.sip.headers) then add .xxx to the function (xxx being whatever you want to name the header.

I couldn’t remember the name of the variable, so I had to look it up 🙂
