It depends on the type of phone system you are looking for. A small business might only need a few phones and a basic system, while a larger company might require a more complex setup with numerous extensions, voicemail boxes, and other features. Generally speaking, though, you can expect to pay anywhere from a few hundred dollars to several thousand dollars for a new phone system. It's important to shop around and get quotes from different companies before making a purchase, as the cost of the systems can vary quite significantly.

It depends on the size of the business and what features are included. For a small business, a new phone system might cost anywhere from $200 to $1,000. For a larger business, it could cost tens of thousands of dollars. Some common features that businesses want in their phone systems include: automatic call routing, voice mail, faxing, caller ID, and conference calling. The price of each of these features will vary depending on the system you choose. Make sure to ask your vendor for a breakdown of costs so you know exactly what you're getting.
