When you use Call Classification after Answer, do not use SBS to route calls. Do not use SBS because the Call Classifier must be on the bearer trunk, and the SBS-invoked DTMF signaling that is sent on the bearer trunk causes interferences.

Adjunct Switch Applications Interface (ASAI) Phantom call, such as DEFINITY Anywhere, can originate or receive an SBS call.

ASAI Selective Listening works on an SBS trunk party on a call.

ASAI Send DTMF works on a connected SBS call.

ASAI Single Step Conference can add another station onto a call with an SBS call.

ASAI Provided Dial-Ahead Digits work when the incoming call is an SBS call.

Any ASAI user data, Universal Call ID, or both that are currently transported or interworked over QSIG trunks, are sent on the SBS signaling call.

Any II Digits that are received in the SETUP message to the incoming SBS Signaling call are tandemed with the SBS signaling call when an SBS call is received and subsequently tandemed over an SBS trunk.

The information that is provided in response to an ASAI Value Query indicates whether an SBS trunk or an associated bearer trunk is idle or busy. The response is based on the UID in the query message and whether the response was for the signaling or the bearer trunk.

For ASAI Event Reports, Communication Manager reports the Call ID and the Trunk ID of the SBS trunk. ASAI provides the Trunk ID of the associated bearer trunk to the ASAI Event Reports and Adjunct Route message.
