ASAI and Call Control

If the outgoing trunk is administered as “network” [as in the case of a private network with cascading ECS (s)], the call will fail; that is, the “user” end will drop the call because the “network” trunk of the ECS does not provide a CONNect ACKnowledgement.

PRI trunks should be accessed by Switch-Classified calls using AAR/ARS. The use of TACs to access PRI trunks is not supported. Also, TAC dialing cannot be used on Switch-Classified calls that are placed on trunks that use MFC signalling. Use AAR/ARS to place Switch-Classified calls over MFC trunks.

Call Parameters for Switch-Classified Calls

This section contains the ASAI interface call parameters for Switch-Classified calls.

orig_addr

dest_addr

dest_route_select

priority_calling

max_rings

direct_agent_call supervisor_assist alert_order

ans_mach

[mandatory] The originator must be a valid local extension number associated with a split, hunt group, or announcement, or a VDN in an EAS environment.

[mandatory] The destination can be a valid ECS extension or an off-ECS destination. It may include TAC/ARS/AAR information.

[optional] This parameter contains TAC/ARS/AAR information for off-ECS destinations if the information is not included in the dest_addr.

[optional] If present, a priority call is placed if the destination is an on-ECS extension. If the priority flag is specified for an off-ECS destination, the call is denied.

[optional] This parameter designates the number of rings that are allowed before classifying the call as no answer. The minimum number is two, the maximum number is 15, and the default is 10 (if not present). A typical ringing cycle is six seconds (this is an approximate value).

This parameter must not be present.

This parameter must not be present.

[mandatory] This parameter must be set to indicate “destination first.”

[optional] This parameter (if present) indicates that answering machine detection is desired and the treatment that is to be applied to the particular call. The treatment options are “drop,” “answer,” or “administered treatment.”
