Videoconferencing
The videoconferencing market essentially splits into three broad segments – endpoints, infrastructure and installation – with further segmentation in the endpoint (personal, set-top and group systems) and the infrastructure (i.e. H320, H323, gateways, gatekeepers) sectors. Increasingly, videoconferencing is being merged into a broader market, called digital video communications, with major manufacturers now moving to supply video, audio and data communications in integrated packages to companies and to move their offerings away form ISDN systems towards IP networks.

Voicemail
A Voicemail system provides an individual answering service for each member of staff. It allows callers to leave voice messages in individual mailboxes when people are away from their desks, out of the office or engaged on another call. Messages can be retrieved internally through your desktop phone, or externally if you are absent from your office.

Voicemail is pretty much a standard integrated feature with most telephone systems these days, although it is available in a variety of formats so it is worth discussing the options with your chosen supplier.

VoIP (Voice over IP)
VoIP eliminates the need for separate voice and data networks by converging all traffic into one network. Both voice and data traffic can be transmitted over a common IP network to provide companies with fully integrated communications. Adopting VoIP can offer your company a variety of benefits such as improved communication between offices and remote locations, the ability to introduce new network applications and make significant cost savings through more effective use of your company’s network.

You should consider purchasing an IP-based telephone system if you wish to network multiple offices using a PBX-to-PBX communications, if you have or want just one infrastructure that can support voice and data between two or more locations, want a smooth migration toward VoIP and investment protection, would like to allow remote workers to become part of the centralised telephone system and share common functionality, or if you are looking to carry out a major upgrade to your existing data network.

VPN – Virtual Private Network
Usually refers to a network in which some of the parts are connected using the public Internet, but the voice and data sent across the Internet is encrypted, so the entire network is “virtually” private. Organisations with offices in more than one location can link phone systems in a VPN. Using a linked numbering plan, a staff member in one location can dial a colleague at another office just by dialing their extension number.
