MegaFon company has made unavailable the service "Multifon" to individuals. Earlier it was possible to buy a SIM card to make and receive calls via sip. Put IVR menu using freepbx for example. It was used by many small companies. Now if you log on as a individual entity, in the *137#, you cannot access your room via sip. Old customers, this service is renamed to "Multifon Business", and is still functioning. New alas, is available only "eMotion calls". What are the alternatives to Tifon you know in 2018?
Need a pool of 100 numbers, the dynamic call-tracking was intended to do. Previously, it was possible as a individual entity to buy 10 SIM cards and one-time to pay 80 rubles for a room with a rate of "go to zero", I did so, now it's closed apparently. To connect Jur.face and pay in the best cases 100 per month for a SIM card comes out expensive. For 10 000 roubles a month easier through some sort of service to do it all. The easy way is not for me, looking for an alternative to tifon.
Look for old customers and ask them to renew their contract on himself so his idea too.
