Wholesale Telecoms

Wholesale termination differs from other types of termination only in terms of volume and authentication methods. Typically in a wholesale environment, a large amount of traffic is emanating from from a few customers, and the focus needs to be on throughput.

Often with wholesale, the charging mechanism is a simple one, with no free minutes, connection charges, or stepped charges. A2Billing can supply a commercial alternative version of calling A2Billing without these features in order to raise the throughput for a given piece of hardware, at the expense of only allowing charging types of x cents per minute.

Many switching platforms, A2Billing excepted, do not allow username / secret style authentication, so A2Billing allows Wholesale customers to authenticate on the basis of their IP address and / or a minimum 5 digit customer code.

As with other systems, A2Billing’s capacity can be increased not only by changing to the Wholesale version of A2Billing but by also splitting out the components of the system by hosting the telephony engine on one of more servers, referring back to the same high capacity database or database cluster.


Vertical Integration

When considering providing wholesale services, it is possible to add in a Reseller Edition of A2Billing, so that not only can the carrier provide minutes, but also provide the switch and billing system to their customers so that they in turn can provide end-user services and sending the minutes to the wholesaler. Furthermore, Star2Billing can license their training program to Wholesalers wishing to sell virtual billing systems to their customers.
