hi all, Does anyone of you know how to setup a Trunk so that a diversion header is created? When a subscriber does a diversion either via vertical code or from the user management interface and someone calls that number that is diverted to the PSTN over the SIP Trunk it would be greate to have on the outgoing INVITE to the PSTN a diversion header with the diverting subscriber and the reason of the diversion like cfu. The are some SIP Trunk Operators that in this case of a diverted call would bill the call on the diverting number, but to achivie this there should be a diversion header. Your opinion and help are highly appreciated. BR - Miguel
