Softswitch Architecture
The architecture of A2Billing consists of a database server, Asterisk telephony server and a web-server for administration, agent, customer and online sign-up. Usually these servers are hosted on the same physical hardware, but can be distributed across multiple servers to increase the capacity. A SIP proxy can be added to load balance calls across multiple Asterisk servers and assist with NAT traversal.
