Cisco IP Phones are a smart investment for just about any business. When making such an investment, it is wise to take the time up front to consider if there are any peripheral accessories that you will need to help your company see the maximum benefits from your Cisco phone installation.
Certain Cisco phone accessories probably go without saying, such as a power cord. If you are not installing your Cisco phone on a PoE switch, you will need to purchase a power adapter. If your phone users will be on the phone for more than 2 hours a day, you should also consider purchasing a Cisco Phone Headset.
