Redundancy - allows You control maintain services, through the use of two devices Call Manager, joined as a one logical system. The system enables the control mode protected against hardware failure or road junction. In the case where one of NCP-CM fails, the other takes over the role and provide control for other devices like NCP-GWx, phones etc. In redundant mode, there are two types of Call Manager:
- MAIN - set up as a "master"
- BACKUP - set up as a "slave"
We distinguish between the two types of operation:
- RUNNING - active, which currently controls the operation of processes and equipment;
- STANDBY - standby mode, in the case information about the failure of the MAIN Call Manager enters RUNNING..
How to connect
The two devices are connected to two interfaces INT and RDU
