Redundancy Solution

Two MyPBX could be optimized for use as a failover system which could provide rapid failover in the event of system failure. Once the active server failure is detected, all the telephony would be switched to the standby server automatically. Thus the downtime was kept to an absolute minimum to ensure the normal operation of all the functions for users.

                                                          Figure 1

Note: MyPBX Standard(v6 or upper)/U100/U200/U300/U5XX support Redundancy.

Note 1: Before enabling the Host Standby feature, please make sure that the two servers in the failover pair are the same model, have the same modules installed in the same slots, the same hardware configurations and firmware version.

Note 2: Please configure the primary server first and configure the secondary server only after the running status of primary server becomes “active”.

Note 3: The virtual IP address inputted in this page will be the one used for registering in each IP phone.

Note 4: Before configuring the Email list in this page, please configure the “Voicemail Settings” in “PBX--Basic Settings”, and make sure the SMTP test is successful.

Mode: Primary means the main unit; Secondary means the standby unit;

Secondary/Primary Hostname: If this unit mode is primary, then you need to input the hostname of standby unit; vice versa, if this unit is selected as secondary, then the hostname of primary unit is required. In brief, you need to input each other’s host name in this field.

IP: You need to input each other’s IP address in this field.

Access code: To make an identification number to verify each other. The number must be the same to both units.

Virtual IP address: Fill in a virtual IP address including mask, which always points to the currently activated unit. Customer can register IP phones through this virtual IP address. Please make sure the virtual IP address including mask is the same on both units but different from their former IP address.

Network Connection Detection: Generally it requires the IP address of the router or gateway that connects both units. MyPBX will connect the other unit through this IP address.

Down Notification: The way of informing customer that the system breaks down.

Keep Alive: Every 2 seconds, a package will be sent from one unit to the other, which can test whether they are working properly.

Dead Time: The default setting is 120 seconds. If there’s no response within 120 s after one receiving a package from the other, then the normal working unit will figure the other unit is dead and send an email to report the failure.

Disk Synchronization: It works for synchronizing the data on hard disk only, such as the call recording files and CDR files saved in disk. The configurations in MyPBX will not be influenced by this feature. Two options are available: timing synchronization and real-time synchronization.

Follow the steps below to set up on the hot standby page:

Step 1: Verify the basic information of the server.

                                                              Figure 3

Step 2: Configure the IP address and hostname of the primary and secondary servers.

                                                               Figure 4

Step 3: Configure Hot Standby Settings.
