Traders

From traders’ perspective, TPO Cluster is almost invisible.

During the failover, a short glitch in the sound will be heard on each call hosted on the failing TPO.

The TPO Cluster will NOT restore non-established outgoing calls. E.g. an outbound call placed through DDI sharing will NOT be restored unless the remote party has accepted the call from TPO point of view before the failure occurs. Once the call is accepted, the call will be part of restored calls in case of TPO failure.

Administrator/users must keep in mind that the same principle applies to all non established outgoing calls i.e. transfer sequence, conference sequence and so on.

Turret Administration

The cluster is working using TPO DNS name – registered dynamically - for active nodes.

Turrets configuration will use TPO DNS name.

A TPO cluster must have at least 3 nodes and maximum 7 nodes. i.e. N+M >= 3 and N+M<=7
