ASAI and Domain Control

Denial (NAK) Causes

Invalid association (CS0/81) — The association does not exist.

Invalid number (CS0/28) — The specified call_id is within the allowable range but currently not active in the ECS.

Mandatory IE missing (CS0/96) — A required parameter is missing in the request.

Invalid IE contents (CS0/100) — The call_id is outside the allowable range for the DEFINITY ECS or the call option IE value is other than ‘Alert Order’ or ‘visibility’.

No user responding (CS0/18) — The station to be added does not go off-hook within 5 seconds or cannot be forced off-hook.

Message not compatible with call state (CS0/98) — A Single-Step Conference is received with full visibility option when the call is in vector processing. This also happens if the call to which a party is to be added, is not in the proper state (for example, parked), or receiving the dial tone. Additionally, Single-Step Conference cannot be invoked, when the call is in the process of being classified by the ECS.

User busy (CS0/17) — The party to be added is busy on another call, has dial tone, or is in the process of dialing a call.

Reorder/Denial (CS3/42). Maximum number of parties allowed on a call has been reached. Also sent, if a request is made to Single-Step Conference to add a device onto a call and the device is already on the call.

COR check fail (CS3/43) — The COR checks for the call and the added party fail.

Bearer capability not available (CS0/58) — The call has conference restrictions due to data-related features, for example, data restriction, data privacy, and manual exclusion.

Protocol Error (NAK)Causes

The ECS issues the following cause for generating a protocol processing error:

Protocol error (CS0/111)

The Q.932 protocol has been violated or the capability invoked is not consistent with this association. For example, invoking the Third Party Make Call capability on a Domain Control association.

NOTE:

For more information regarding protocol errors and a complete list of reason codes (cause values), see the DEFINITY Enterprise Communications Server CallVisor ASAI Protocol Reference, 555-230-221.
