- Servers 1 and 2 (S1 and S2) are identical. They server as gateways with Asterisk + MOR installed.
- Both of them have two network interfaces - one for Main IP which is visible from outside, and one for local IP for interconnection (heartbeat monitoring)
- LinuxHA heartbeat monitors servers, e.g.
- When S1 fails - S2 sees that and after 10s (default) will take main IP, e.g. will start to serve calls, it is done automatically
- When S1 is back up - S2 returns main IP to S1 and system starts to function in normal work flow (done automatically).
- Servers 3 and 4 (S3 and S4) are identical. They server as MySQL DB.
- Both of them have two network interfaces - one for Main DB IP which is visible for Asterisk servers S1 and S2, and one for local IP for interconnection (heartbeat monitoring)
- LinuxHA heartbeat monitors servers, e.g.
- When S3 fails - S4 sees that and after 10s (default) will take main IP, it is done automatically
- When S3 is back up - S4 returns main IP to S3 and system starts to function in normal work flow (done automatically).
- DBs on S3 and S4 are synchronized over MySQL Replication
