How to hide the number of the buyer from the seller?

I play the role of aggregator and I need to get a number of the buyer to the seller.
How to do so:
  1. The buyer left his number on the website
  2. I swapped it and gave the seller
  3. Then when you call the buyer from the seller on the spoofed number, the vendor number is replaced too
  4. After completion of the transaction between them, the numbers they got, they were met by an answering machine or something like that
  5. Also a nice advantage is the ability to record these calls

Is there any already ready decisions on this subject or how I implement it is the most cheap and simple? Thanks in advance!

Your switch and numbering capacity to solve this problem. Assign the vendor number and customer number for one time room of its capacity and will forward calls to the temporary number corresponding to the real numbers.

Asterisk will help you. Call recording and answering machine comes.
And how much it will cost, will not prompt? - nikita.Stracke commented on June 5th 19 at 21:31
if the integration with the website to make smart, i.e. the main logic to move there and then Aster will be almost like a media server.

One common room + enter the code of the buyer.
Common room landed on Asterisk. The buyer code is verified using key-value DB (built-in *).
A lot of rooms (though ABC, though DEF) cheaply, no one will sell, and they need to cover the number of concurrent "transactions" for the maximum duration of a transaction.
