Who uses a multiphone?

Question

Telephony

If they call me from cellular to cellular
(sim card of a megaphone with the multiphone service connected),
should I have a parallel call to the computer where the multiphone is running?

Answer 1

I set the forwarding of incoming calls to Multifon and GSM, called, the tablet and phone rang at the same time.

Answer 2

The website of the multiphone says what's what. It is possible to direct all calls to the phone, to SIP, or both there and there. How to set up is also written on their website.

Answer 3

The problem is that for 3 days in technical support they convince me that this is impossible !!!
Therefore, I want to ask those who use whether this scheme works or not
