Need to setup a scalable asterisk server which can handle minimum of 200 missed calls per second ( outgoing ) .
I can buy DID's from a provider you suggest
I can buy 2 or three voice termination server you suggest
i will provide a ubuntu server instance with root access
You have to create a user friendly config file / database to add new voice termination credentials details and DIDs ( not familiar ) and need to create an API
from_number = A random DID hat i'll set
to_number = international mobile number
call_back_url = POST the STATUS of missed call to the url i will pass like ANSWERED, REJECTED, NOT REACHABLE, NO ANSWER . if answered amount SPENT for that call .
The calls should get disconnected on first RING . if ANSWERED hangup in 3 sec .
