Called number
The originally called extension if a call is forwarded to a VDN, or the first VDN through which the call was routed if the call was not forwarded to the VDN.
If the VDN Override for the Trunk ASAI Messages feature is in effect for an incoming call, the active VDN extension (instead of the Called Number received in the SETUP or INVITE message) is sent in the Called Number for the Call Offered, Alerting, Queued, Connect, and Adjunct Route-Request ASAI Event Reports.
