How to organize telephony for an online store?

Question

Telephony

I want to organize telephony for my online store.
Previously, the girl sat on three different mobile phones and answered calls along the way, looking for all the necessary information.
How I see it:
1) I buy 3 different sims
2) I tie them to a virtual PBX
3)
is this possible?
the purpose of this is that all numbers become multi-channel and the girl receives all calls through a PC, simultaneously
recording and registering in the customer database and their data.
you also need:
1) Recording conversations
2) Setting up an answering machine that would work if no one is available
3) Receiving SMS
4) Sending SMS
5) Distributing calls between operators
I would like to get advice or feedback about the offices that do this.
Maybe someone has experience in the implementation of
PS
so far is specifically interested in Ukraine, since we work only in one country.

Answer 1

It is easier to do this through a special company that specializes in this.
Or even through a carrier. Let's say Beeline has 100% multichannel. It just needs to be connected.
