I am using AMI Originate to perform a new outbound call.

The SIP Provider we send the call to wants us to pass the caller id of the person we are calling for in the Contact header.

For the AMI Originate, I pass the caller id information data in the CallerID field. However, this is never being passed through the PJSIP INVITE header

Action: Originate ActionID: S598
Channel: PJSIP/133@1002
Exten: createcall Context: MyContext Priority: 1
Timeout: 60000
CallerID: CustomerName <########## >
Variable: CALLERID(num-pres)=allowed_passed_screen,TrunkAllocateId=5,OriginateCallId=396
Async: true

Is there a setting that’s required on the PJSIP endpoint to allow overwriting the INVITE packet’s Contact header?
Is there something else I am missing to perform this?

Have a great day!

Dan
