OneCore · Wholesale softswitch

Wholesale switching with billing built in

OneCore is a softswitch for carriers, resellers and wholesale voice businesses. It sits between your customers and your upstream carriers. Every call is identified, priced and checked against the customer's balance before it connects, then sent down the cheapest working route.

How a call is handled

1. Identify: the caller is matched by carrier IP, customer IP or SIP username and password.
2. Rate & check credit: the destination rate is looked up, the balance is checked, and a maximum call duration is set from the credit available.
3. Route: the call goes to carriers in least-cost order. If one rejects it, the next is tried automatically.
4. Bill: the call is billed to the second, and it is cut off one check before the credit runs out, even when a customer has several calls running in parallel.
