Is it possible to connect IP telephony in not very large cities of Russia?

Question

Telephony

The question is for those who have long been familiar with the organization of IP telephony and know the market development trends.
The offices of our company are located in more than 30 cities of Russia (including not very large ones: Abakan, Belovo, Blagoveshchensk, Kyzyl, Neftyugansk, etc.)
The problem is this: we use the Telfin service, in which not all cities can connect virtual number (you need a local number, not a federal 8-800-). A cursory study of the situation on virtual numbers did not give any results (I found out that local numbers are provided by local providers and not everyone has the necessary equipment to ensure the connection of a virtual number, so such numbers cannot be rented from intermediaries like Telfin). If someone has something to add, please share the information.

Answer 1

receive numbers in offices by yourself and drive them into your IP telephony only
