There are three main customer types for Voice over IP, and A2Billing supports all of them with flexible VoIP Billing and charging options.
Residential VoIP - Providing VoIP services, VoIP Billing and DID redirection to the general public. The endpoint is usually a PC-Dialler (or softphone) a physical VoIP phone or ATA. The latest smartphones also support VoIP.
Business VoIP - Providing VoIP termination to IP-PBX systems for companies, billing the calls, as well as providing invoices for VoIP services as well as supplying DID directed to the IP-PBX via VoIP or PSTN.
Wholesale VoIP - Terminating and billing large numbers of calls from a customer who has an A2Billing Softswitch or similar class 4 or class 5 switch.
The only difference between the above types of service as far as A2Billing is concerned in in terms of volume. Configuration is broadly similar for each service.
The A2Billing Softswitch supports both the SIP and IAX2 protocol as well as a range of VoIP codec protocols, such as g711 which is a high quality uncompressed codec. Where bandwidth is limited, the supplied GSM codec can be used or commercial g729 licenses or g729 voice compression cards for high capacity systems are available.
The customer’s end-point is configured to pass its VoIP traffic through the A2Billing Softswitch, where the call is then least cost routed via the lowest cost carrier, the call is rated, and the customers available balance decremented.
