How to negotiate Termination

I have a new VOIP business model/service I'm trying and I don't quite understand how to choose a VOIP termintation provider that suits my service's needs, what to ask for, and how to negotiate and recognize a good deal. I understand that this is about "last mile" of the call, and usually delt through wholesellers. We will also want to offer DID's and use a SaaS telecom billing solution for a VOIP (SIP) to PSTN service. We want people to call originating from the US, Canada, Australia, UK and Poland to most popular call destinations.

Can anywone please explain how to go about this? A detailed plain english description would be MUCH appreciated!

Thanks in Advance

Start with your own end user. Find out what they need, then seek a supplier accordingly.

To be honest asking a question like that prior to entering into a business with it concerns me somewhat. Are you sure you know what you're doing? You could be about to lose a whole load of money (most do)....
