HI
I explain, the lowest rates you can offer is buying other sellers of gray routes that have excellent quality, there is no other way since the cost of interconnection is very high and is what makes the price per minute is high clear we must Keep in mind that with the interconnection with a certified operator and enabled for mobil and fixed telephony you will have an extraordinary quality and you will not have problems of fall or unexpected cuts of the route.
I put an example in my case I sell VoIP telephony and I buy minutes to recognized operators that have Tier1 interconnection that covers an AtoZ and I buy routes to many operators of gray routes that are of excellent quality to be able to compete in the market and according to Either the customer will deliver one and / or another route with different rates. Example: if it is for a company I provide high quality with a premium route that has a value between the gray route and the direct interconnection route but it allows me excellent quality good ASR +60 ACD +8 and PDD -6 but if I am going to use a route for calling cards I can do a mixture of both routes and if the traffic is only to the one in May I use the gray route that is stable and a higher profit margin And we all won.
Buy and Sell Call Termination:
At this point there is a greater complexity since it is not buying and selling by chance it takes the experience and knowledge of many elements that play an important role when it comes to comparing and selling minutes, ignorance of the matter can lead to a great loss Of unimaginable money, is a work that can be performed by a single person when you have the necessary knowledge of the areas that involve the purchase of the sale, if you do not have the appropriate experience, it would be advisable to have a working team in each area. Way that allows the fruit of the work.
We have a universe where there are all distributors, buyers, suppliers either of gray routes or with direct or indirect interconnections usually do not sell their traffic to the end user because they would have to invest much more in infrastructure to be able to meet that demand all of them prefer Sell their wholesale traffic so they only serve a limited number of users and focus more on the quality of the routes lower their costs and earn much more money in less time.
I hope this explanation is useful
