ASAI and Domain Control

Redirect Call

The adjunct uses this capability to re-route a call that is already alerting a station extension.

Information Flow

The adjunct expects a response to its request.

The ECS either:

Redirects the call and drops the alerting party after validating the parameters, or

Denies the request and maintains the alerting party

Domain Control Redirect Call Parameters

[mandatory] The call_id of the call to be redirected

redirected-to[mandatory] Identifies the number the call is routed to (may

-numberbe on or off-ECS). If more than 24 digits are provided, only the first 24 are used.

ACK (Positive Acknowledgement) Parameters

An acknowledgment is sent to the adjunct if the request is successfully completed and the call stops alerting the redirecting station.

The redirected-to number or other IE is missing in the request.
