Could someone suggest a good VoIP provider for me?

Specifics:
Unfortunately, I am not well-versed in the realm of VoIP. However, we require a service that furnishes one telephone number to divert calls to four handsets (for now) at a fixed location where we don't have a phone yet. Additionally, it would be great if the incoming calls can also be redirected to a computer.
It's important for these mobile phones to be set to not ring during certain times and for the IVR (I believe that stands for Interactive Voice Response), which can play music or give users a message, to be available periodically. This feature would be helpful but not critical.
That's pretty much all we're looking for. But, please don't hesitate to ask if you have any questions, and I'll do my best to provide answers.

What country would you prefer your phone number to be associated with?
While my current VoIP provider has a user-friendly interface for creating a program, it only offers dedicated phone numbers in a handful of countries, specifically within Europe.

Having a phone number that is associated with a particular country can be important for businesses that operate internationally or for individuals who want to make it easier for people in a specific location to contact them. One potential solution for this challenge is to use a virtual phone number service, which can provide local phone numbers from many different countries. This can help to create a professional appearance for your business and simplify communications with customers and partners abroad.
