Set CallID for DIAL on chan_sip


is it possible to set the callid to some specific string when placing a call on chan_sip with the DIAL cmd?
I am NOT refering to the CallerID (CLI) but I mean the INVITE’s unique callid element.

Thanks for your help!

Do you mean the caller ID that the person on the other end recieves. Something like ?

Exten => X.,1,SetCallerID(${VARIABLENAME})

Sorry, I just realized that I was missing the word “NOT” in my last sentence.
So I am NOT referring to the CallerID but to the SIP callid.

Thanks for taking the time to answer anyway!

Best regards,
