If the communication of a Lotus Sametime Unified Telephony cluster node and its billing network fails - that is, if both billing Ethernet ports of the Linux bonding driver are unavailable - the consequences depend on the file reporting mode.
The consequences of losing the billing network interface on a Lotus Sametime Unified Telephony node depend on whether billing files are reported via push or poll mode:
Push: If the Lotus Sametime Unified Telephony pushes the billing file and does not get a response, the CDR Handler node tries another billing server IP address and, if unsuccessful, switches over to the other node.Parent topic: Cluster Redundancy
Poll: If the active CDR handler runs on the node with the lost communication, the external billing server cannot read the CDR files. The Lotus Sametime Unified Telephony is dimensioned to store billing files for 5 days. If communication cannot be re-established within this time, the craftperson should manually switchover the CDR-handler process.
