Cordless VoIP Phone

Cordless VoIP phone - modern communication without cables

What is a cordless IP phone?

An IP phone uses Internet Protocol (IP) to transmit voice data over networks. Unlike traditional telephones that operate on the public switched telephone network, an IP phone converts your voice into digital data packets and sends them across your company network or the internet. All of this without the hassle of cables or wires.

IP telephony and VoIP - briefly explained

Voice over Internet Protocol (VoIP) is the technical foundation of modern IP telephony. Here’s how it works: when you speak, the microphone in your IP phone captures the sound waves and converts them into electrical signals. An integrated codec compresses these signals into digital data packets, which are sent over the network to the recipient. There, the packets are converted back into audible speech.

The Session Initiation Protocol (SIP) plays a central role as the standard for signalling and controlling VoIP connections. SIP sets up, manages and ends calls, while also enabling advanced features such as call forwarding and conference calling.

Wi-Fi phone: a cordless VoIP phone with built-in WLAN

Combining Voice over IP telephony with Wi-Fi connectivity opens up new possibilities for mobile communication in the office. Modern cordless VoIP phones include integrated Wi-Fi modules that connect directly to your corporate network. This means you can move freely within your Wi-Fi coverage without compromising call quality.

Wi-Fi functionality can operate alongside traditional DECT technology, enabling seamless handover between different base stations. This dual-mode approach ensures optimal reachability and mobility.

Frequently asked questions (FAQ)

1. What’s the difference between a cordless VoIP phone and a traditional phone?

A voice over IP cordless phone uses Internet Protocol to carry voice over networks, while traditional phones use the classic telephone network. IP phones offer advanced features, cost benefits and better integration with modern IT systems.

2. Will a cordless IP phone work without the internet?

No, cordless VoIP phones need a network connection for VoIP features. However, some models can also operate as standard DECT phones with an analogue system if configured accordingly.

3. Do I need special network equipment for cordless VoIP phones?

Generally, cordless IP phones work on standard network infrastructure. For optimal call quality, a network with Quality of Service (QoS) and sufficient bandwidth is recommended.

4. Can I keep my existing number when switching to VoIP?

Yes, number porting is usually possible. Speak to your VoIP provider about moving your existing business numbers during migration.

5. How secure is communication over voice over IP cordless phones?

Modern VoIP phones support security protocols such as TLS for signalling and SRTP for media encryption. With correct configuration, they offer at least the same level of security as traditional telephony.

6. What internet speed do I need for optimal VoIP quality?

Allow roughly 80-100 kbps per call. For multiple simultaneous calls and extra features, budget additional bandwidth, ideally with QoS prioritisation.
