The VDN Override for Adjunct-Switch Application Interface (ASAI) Messages feature affects the following called number ASAI message information:
Call Offered
Alerting
Queued
Connect
Adjunct Route-Request
Important:
Communication Manager activates this feature for an incoming ISDN trunk call when Communication Manager routes the call to a VDN that has the VDN Override for ASAI Messages field on the Vector Directory Number screen set to ISDN Trunk. To use the VDN Override for ASAI Messages feature for ISDN trunk calls and internal calls, set the field to all.
When Communication Manager activates this feature for a call, this feature remains in effect for the call regardless of the VDN Override for ASAI Messages field setting for subsequent VDNs to which the call is routed.
The VDN Override for ASAI Messages field setting affects the called number information in the following manner:
If you set the field to no, the called number information is the called VDN extension in the called number Information Element (IE) sent in the incoming ISDN SETUP message or the local call number and does not change after routing to the called VDN and to subsequent VDNs.
If you set the field to ISDN Trunk, when an incoming ISDN trunk call is routed to this VDN, the called number information sent in the ASAI event and Adjunct Route-Request ASAI message is the active VDN extension that becomes associated with the call based on the VDN Override rules. This field option does not apply to internal calls.
If you set the field to all, the active VDN is used for the called number for all types of calls to the VDN including internal calls and incoming ISDN trunk calls.
