Rolling ASA follows the rules used for other Advanced Vector Routing conditionals to specify a VDN in a goto step:
A VDN number.
The value designated as latest. The latest VDN is the VDN currently processing the call. The latest VDN is not affected by VDN override settings.
The value active. The active VDN is the VDN of record, which is the called VDN as modified by override rules. For example, if a call routes from a VDN with override set to yes then the new VDN is the active VDN. If a call routes from a VDN with override set to no, the previous VDN is the active VDN.
