The Components of a VoIP Hard Phone

Although
some VoIP hard phones may resemble traditional desk phones, they
provide users with enhanced QoS and security. While ATA adapters allow
users to reuse old analogue devices, VoIP hard phones have been designed
to work over the internet, making them the best solution available.
Unlike softphone alternatives, such phones also operate independently,
meaning they do not require a computer to run. The following components
define VoIP devices:

• IP protocol compatibility and data encryption software
• RJ-45 ports (LAN) and RJ-11 ports (PSTN); Ethernet may be used to route the device to a PC for unified data usage
• A keypad/touchpad for placing calls -- some devices come with LCD screens and programmable feature keys
• Speaker, receiver, and headset jack for hands-free usage
• Batter, AC, or Ethernet power supply

Different VoIP Hard Phones

VoIP devices vary in capability. The
features discussed above outline what you may find in the most basic
VoIP hard phone. These are great for entry-level users who do not need
full system access. Intermediate devices, however, incorporate more
buttons, allowing further independence away from the computer.
Higher-end devices may even include colour displays, touch-screens, and
video telephony support.
