SIP trunk, what do you still need to pay for?

Question

Telephony

What is the cost of this service?
The provider sets the price he wants?

Answer 1

Well, yes, this is a commercial service. As the provider wants, it will charge a fee.

Answer 2

They calculate how much they have costs, the payback period, and sprinkle the amount on top for income.
Something like this:
The cost of the purchased equipment (divided by the likely period of its operation and the number of customers) + the cost of maintenance (salaries to everyone, taxes) + the cost of repairs (probable in the event of an emergency) + the cost of SORM + the cost of renting rooms, etc. etc. All this is divided by the number of clients. And this is the final cost of the service.
Nothing is taken from the air, and just like that, no one draws a price tag for a service from a bulldozer, at least where everything is legal, clean and white according to the letter of the law. Unless, of course, a semi-legal type of opsos bought a bunch of gsm gateways, poked into them sim cards obtained from no one knows where, at the very least on his knee made it all work and then sells it. But here you need to understand that this is illegal, for this you can thunder like a client, no one guarantees anything.
