Just got off a fairly disappoint call with TAC. After reviewing the basic setting of Callmanager/Unity Connection SIP integration, the engineer confirmed the configuration look correct. He then informed me that Unity cannot provide a diversion header. I think he was basing this of not seeing a setting on Unity to enable Diversion Headers.<div>
<br></div><div>This is a common requirement for SIP Carrier to include a authorize number in the diversion header to support offnet to offnet transfers. Unity does not support sending a diversion in the SIP trunk Msg?</div>

<div>We are seeing an issue where when call are are transfered from our Unity to Verizon SIP trunk calls will fail. Call that get transfered back to Verizon will require a diversion header that contains a authorized ANI and from our CUBE IP address. We have this working with calls to IP phones that transfer back to the PSTN. Unity is not providing a Diversion header. Has anyone else run up against this issues and resolved?</div>
