IP PBX8000 main and standby redundancy protection mechanism verification method:
For the service test scenario in the dual main control board switching state, the specific test verification method is as follows:
1. Test environment:
The device works normally, and the voice service is normally registered to an IP PBX device A (with dual main control boards) and a SIP server B using the SIP protocol. A normal communication relay connection is configured between A and B.
Configure phone user A0 on the device A side;
Configure the user phone user B0 on the device B side;
IP PBX device A provides dual link access for the uplink. The device is equipped with dual main control boards, and the wan ports of main control board 1 and main control board 2 are connected to an uplink respectively.
2. Business performance test 1: Active/standby switching during the voice call without interrupting the call service
1) Unplug the network cable of the main control board 1 and reserve the network cable of the main control board 2. The phone A0 can successfully pick up the phone to call the user B0 and talk;
2) Plug back in the network cable of main control board 1, unplug the network cable of main control board 2, phone A0 can successfully pick up the phone to call user B0 and talk;
3. Business performance test 2: The switching of the active and standby boards of the session during the connection process does not interrupt the business"
1) Plug back the network cable of the main control board 2. The network cables of the main control board 1 and the main control board 2 are both connected. A wan port network cable of a main control board (for example, main control board 1), B0 calls can be answered normally;
2) Plug back the network cable of the main control board that was unplugged just now, the network cables of the main control board 1 and the main control board 2 are both connected, phone A0 picks up the phone to call user B0, B0 is in the ringing state, and B0 is unplugged during the ringing process Disconnect the wan port network cable of the other main control board (for example, the main control board 1 was unplugged just now, this time unplug the main control board 2), and the B0 phone can be answered normally.
