Choosing the right phone system is crucial for any business, as it impacts communication efficiency, scalability, and cost-effectiveness. Traditional PBX (Private Branch Exchange) and IP PBX (Internet Protocol PBX) are the two primary options available, each with distinct advantages and limitations. Traditional PBX relies on physical telephone lines and hardware to connect internal and external calls, making it a reliable but often costly solution. However, scalability can be a challenge, as adding new lines often involves significant costs and complex hardware modifications.
