Regarding To Basic installations Requirements

[Emam]

Hi connected! This is Emam From Bangladesh i am new in 3cx system .Now i want to know from you, which devices are required for 3cx installation .
I watched some videos but my concept is not clear yet.

It will all depend...do you want to install on a computer/server locally, or have someone host it remotely? Do you want physical SIP phones, or want to use computers with the 3CX softphone, or a 3CX App, running on a mobile?

While a firewall is a good idea, for security reasons, it is not required. You do have to set up port forwarding in the router that 3CX is behind.
As far as calling... that is determined by you, when you create outbound rules, and the agreement you have with a VoIP provider.
You will have to find a provider in your country to get a phone number, and/or DIDs, or, at least, one that offers service there. While you can choose a provider that is not 3CX supported, it is not recommended, especially for someone not that familiar with VoIP.
