- Video Streaming
- See Streaming.
- VoDSL - Voice Over DSL
- Provision of voice communications over a DSL (Digital Subscriber Line) connection. Sometimes referred to as 'Direct Connection' to a service provider's network, via use of a ULL. Typically this connection can also supply a high-speed Internet connection simultaneously.
- Voicemail
- A recorded message service where callers may be diverted. The caller is charged as though they are connected to the number called. For mobile services, the called party may also be charged. (See also Message Bank.) For landlines, voice mail may be provided by the service provider as a virtual service, through a PABX voicemail facility, or through an answering machine. For mobiles, voicemail is applied by the service provider or the carrier.
- Voicemail Box
- Part of the voicemail system where a users messages are kept and managed. This may refer to a PABX voicemail system or to a mobile phone's voicemail facility.
- VoIP - Voice-over Internet Protocol
- Is the transmission of telephone calls over a data connection. Often perceived as voice-over-Internet, several types of 'managed' VoIP exist. Internet Calling is therefore a mere subset of VoIP. VoIP over Internet often has severe limiting quality issues, due mainly to packet delays and packet losses. The quality issues can be decreased by use of an appropriate Internet connection, use of a QoS Router, use of a quality VoIP service provider and use of appropriate hardware. See QoS Router (Quality of Service) also.
- VPN - Virtual Private Network
- A secure network connection between users of differing LANs. A VPN may be constructed over private or public IP networks (such as the Internet). VPNs are becoming an essential tool for mobile employees, and for employees wishing to work from home.
