VoIP Phone FAQ
Yes, a VoIP phone must be connected to either an on-premise VoIP system or a hosted VoIP service for it to work. Always check compatibility with your system or provider before choosing a phone.
No, there’s no difference. Both terms mean the same thing. “IP phone” is simply a shorter way of saying “VoIP phone.”
A SIP Phone is a VoIP phone that uses the SIP (Session Initiation Protocol) standard for communication. Since SIP is the most widely used VoIP standard, SIP phones are the most common type available.
Not always. Most VoIP phones support PoE (Power over Ethernet). If your switch or injector provides power through the Ethernet cable, you don’t need a separate power adapter. If not, then you’ll need a power supply.
One port connects the phone to the network, and the other allows a computer to connect through the phone to the same network. This setup reduces the need for extra cabling and lowers infrastructure costs.
No. Gigabit ports only allow faster data transfer speeds for connected computers. VoIP calls don’t require Gigabit speed to sound good.
HD voice refers to high-definition audio for clearer and more natural conversations. It captures a wider range of sound frequencies compared to standard phones, making calls easier to understand and more productive.
A BLF (Busy Lamp Field) key lets you monitor another extension. If that extension is on a call, the BLF light will show it as busy. You can also use it as a shortcut to call that extension.
Video Conferencing FAQ
Video conferencing (also called teleconferencing) is a live video connection that allows people in different locations to communicate using both audio and video.
VCaaS is a cloud-hosted video conferencing service that works on a subscription basis. These services are more affordable than traditional systems and don’t require special hardware in most cases. Users can join meetings using webcams, headsets, or smartphones. Popular VCaaS providers include Zoom and BlueJeans.
Yes, you need a standards-based video conferencing system from providers like Polycom, Cisco, or Lifesize. Depending on the setup, you may also need cameras, USB speakerphones, and headsets. For large rooms, systems like the Polycom Group 500 are recommended.
A codec is the system that encodes and decodes video conferencing signals. It compresses the video/audio data for transmission and then decodes it on the receiving end. Common codecs used in video conferencing include H.264 SVC, H.264 High Profile, and H.263.
Any modern flat-screen TV can work. However, for frequent or professional use, a high-quality commercial-grade display is recommended to ensure clarity and durability.
Far end camera control allows the remote participant to adjust the camera in your room. This helps them get the best view of you or shared items like a whiteboard.
Multisite video conferencing allows three or more locations/participants to connect in a single meeting.
Point-to-point video conferencing involves just two participants or locations connecting directly.
Content sharing allows participants to share files, documents, or screens (like PowerPoint, Excel, or videos) during a video meeting.
No, it doesn’t always require two displays. With one display, shared content and the video feed appear on the same screen, usually split. If your system supports dual displays, one screen shows the video participants while the other shows the shared content.
