Question

Telephony

Good afternoon!
Advise from whom it is profitable to rent a pool of numbers (In the amount of up to 100 pieces, in codes 495 or 499)?

Answer 1

Sipout.net or zadarma.com if not to worry, sipout has the best prices, but there are jokes with the availability of numbers not from the Russian Federation and from regional mobiles, for most topics this is 1-2% of the total traffic. We can advise you to take high-quality numbers to Mango-telecom, our large customers take from them, but there the connection is longer and you have to pay for their service.
