Telephony

People, help me find a solution.
Initial data: I work remotely, and therefore there are a lot of calls, both incoming and outgoing. Mobile numbers MTS and Beeline.
Purpose: I want to go over the hill, but I want to take work with me.
Task: if you already have given mobile numbers, it is necessary to avoid horse roaming, both for yourself and for the customer. To say so, no one guessed that he was calling to another country.
How to generally approach this issue? maybe it's some kind of redirection.. or ip-telephony...

Answer 2

I don’t know about MTS and Beeline, but since now you can switch to another operator with an old number, I can advise the Multifon service in Megafon: multifon.ru An
application is installed and if you have the Internet, you can forget about roaming. The app's new name seems to be eMotion.
But there are some pitfalls here:
1. The quality of communication is worse than directly by phone.
2. This application does not work smoothly on all devices.
Before deciding to change the operator, you can buy the cheapest SIM card in Megafon and test it. By the way, in order to use the Multiphone, there is no need to put the SIM card into the device you are going to communicate on. A SIM card is needed only to receive an SMS with a code, i.e. She can stand in another device.

If these numbers are needed "by PPC", then it will be necessary to leave these sims here.
As an option, by the way!
1. You switch to tele2
2. you pick up a wifi call (this is a program for the phone)
3. You take the phone away
4. you place it where there is wifi, but there is no network signal
