ARI: add header to reinvite

Hi everyone,

I have an ARI application, and I see that when I add a second channel to a bridge, a SIP re-invite is sent to every sip endpoints of the call.
Is it possible to add a standard/custom header to the SIP reinvite (by using ARI, of course)?

Thanks a lot,
Daniele

There is no ability to add headers after the initial INVITE.
