This page shows some ways how MOR billing system can be used. Examples are from real implementations.

This is the most popular solution because it is fully redundant and most stable.

Stable and redundant solution for high performance.

Such system is in Italy serving Call Shops
E1 hardware is 2 x Sangoma A108DE cards
This implementation is used for high volume calls to/from PSTN network over 16 E1 links were 4+4 E1 is for incoming and 4+4 E1 is for outgoing (on Asterisk 1 server 4 incoming/4 outgoing and same on server Asterisk 2).
Separate server is dedicated to database which minimizes load on Asterisk servers.
GUI is on separate server with it's own DB connected to main DB server over MySQL Replication.

SIP balancer
If one of Asterisk servers fails, SIP balancer routes calls via remained Asterisk servers.
LinuxHA heartbeat monitors Database servers
- When Main Database fails - Backup Database sees that and after 10s (default) will take Virtual IP, it is done automatically.
- When Main Database is back up - Backup Database returns Virtual IP to Main Database and system starts to function in normal work flow (done automatically).
GUI server is connected to Backup Database to avoid load on Main Database in normal work flow.

This solution can handle up to 1000 simultaneous calls. Certain amount of calls may vary depending on hardware, codecs used and transcoding.
