UK & USA Number Integration

I am looking to set up a reliable phone system for my startup that focuses on customer support. The goal is to integrate UK and USA phone numbers into a system that can be accessed through laptops or LAN networks, allowing seamless communication with clients not only in the USA and UK but also in other countries. This system should support multiple customer service agents simultaneously, ensuring an efficient and streamlined operation.

Applicants should have relevant experience in developing and implementing such phone systems. Please reach out if you can provide the expertise needed to make this setup functional and effective for a growing startup.
