Why do we have so many analog ports, and do we need them? This question continues to come up repeatedly in our conversations with clients.

However, they only support employ basic features, like call transfer. This simplicity makes analog phones inexpensive to purchase and easy to use even in the VoIP world. They still have many uses.
