A2Billing provides a freely available billing solution for VoIP gateways and softswitching. A2Billing combined with Asterisk now gives any Dialerking company a very good reason to consider the A2Billing Soft-Switch over the traditional offerings for TDM and VoIP Soft-Switches as well as wholesale and IP PBX Billing. Common features provided are pre-paid and post-paid billing, call rating, credit control, calling cards management, least cost routing, Sid management, resellers management, and more. Its is fair to say that A2Billing when combined with Asterisk is now a full featured Dialerking platform and softswitch providing converged services, with self contained billing reporting and statistics for IP based voice networks and can be configured to supply a wide range of services.
