A.4.4 Call Waiting / Call Queued

A.4.4.1 ISDN-to-SIP Call Queued by the SIP User

In this scenario, the MediaPack receives a 182 Call Queued instead of an alerting

message. If the MediaPack receives a call queued, the MediaPack plays the Queued tone

to the ISDN user instead of the alerting tone.

For this scenario no configuration is required.

A.4.4.2 Call Waiting SIP-to-ISDN Calls

If Hunting is disabled (refer to Section 'Hunt Logic' on page 98), the MediaPack sends a

third setup to the ISDN port. Simultaneously, the MediaPack responds with a 182 Queued

instead of a 180 Alerting. The ISDN user may choose to put the current call on hold and

accept the additional call.

If Hunting is enabled, the MediaPack searches for an available ISDN port. If no available

ISDN port is located, the call fails.

The configuration for Call Waiting is implicit (given by Hunt Logic). No additional

configuration is required or possible.
