Which SIM-bank to choose?

Question

Telephony

Huge hello everyone! First time here, so I apologize in advance if I asked something wrong!

There is the following task: you need to receive SMS and calls 24/7 to 110-120 different numbers. At the same time, it is known in advance to which number an SMS will be sent or an incoming call will be received. You also need the ability to remotely access the SIM and quickly switch between SIMs using the interface.
The only thing I could find on the Internet is a sim bank. But I can't figure out which one to choose. There are simbanks assembled from modem modules in 16, 32, 64, 128 ports (quectel m35). As I understand it, they connect to a PC and do not have the possibility of remote access, and the call is answered by attaching a headset to a specific module, which is inconvenient. There is also an option for the GOIP SMB128 sim bank, but it’s not clear what hardware you need to buy in addition to the gateway (a gateway for 16 ports should be enough).
Here are the questions: Which solution is better to choose, how realistic it is to set up the whole thing without programming skills, where you can read additional information in addition to this article and this one,Is it possible to consult somewhere on this issue and are there any ready-made solutions to this issue?
Many thanks in advance!

Answer 1

In my opinion, if a hundred / hundreds of cards and you want more or less reliability, then you should reconsider the concept and get a joint from the operator.
Naturally, if we are not talking about spammers-crooks.

Answer 2

You need a telephony server (asterisk, freepbx), you can raise it on a virtual machine, or you can use it on your home PC. GOIP SMB128 will connect to it over the network, you configure call rules on the server. GOIP also has software for managing the gateway and working with SMS.
To configure all this, you need to:
- be able to configure linux
- have experience with asterisk
- have programming experience (at least php or python)
