How to add SipAddHeader in outgoing call file.
I am implementing a Callback scenario, in which a user makes a call to
Local Access Number. The  system have to callback to the user. During
callback a call file is generated. All I want, is to add
SipAddHeader("pchargingvector","val") in outgoing Invite.
How can I achieve this?
