What is Wholesale VoIP?
If your a normal user of VoIP services to call your loved ones worldwide, then you may not know what it takes to setup the service to be used. It requires many technical personal that know how to handle a big server. But apart from the setup, wholesale VoIP termination is a very important aspect of this business. Wholesale providers receive interconnection from countries and they resell that to providers like uVOIPit.
These providers negotiate costs with countries depending on the amount of traffic (minutes) they send to that country. The more minutes the less the rate. Then they set there profit margins and resell to VoIP services. This is all done via IP authentication. IP is given by the server provider such as HostGator or GoDaddy. The wholesale VoIP providers give the services a CDR (Call Directory Records), to check the calls going through so they can track there balance.
The services pay the providers for the minutes used via wire transfer or other methods. Wholesale providers either work prepay or post pay payments. This is up to them on what route they choose to take. There are safety precautions that they take to be safe from fraudsters.
Wholesale VoIP is the part of reselling to other companies. Therefore, wholesale VoIP providers deal with businesses and not with individuals like you and I. They are there to give big corporations interconnection with countries.

IP Authentication
IP authentication is very important in the wholesale area. Asterisk, or the cornerstone of VoIP industry, must be able to recognize an IP sending calls. Sometimes this is misused alot and different IPs send calls and Asterisk accepts it. This will need to be prevented or the provider will lose money.
In Asterisk files, the IP of the different server will need to be set then it will be authenticated when calls are sent through. This is the hardest part to setup because it requires knowledge of Linux, servers, and commands. The other parts are easy because you get to use a graphical interface.
It is always good to use a provider because it takes out the hassle of having to handle relations with different countries. Above in the table are very good providers. Try one of them if your looking for good interconnections.
