Draytek Vigor 2800V ADSL2/2+Router VOIP Annex A ADSL wired router

Vigor 2800V ADSL2/2+Router VOIP A The DrayTek Vigor2800V has all of the features of the Vigor2800 ADSL router with the addition of two phone sockets, to provide Voice-Over-IP (VoIP) facilities. VoIP enables you to use your existing broadband capacity to carry regular voice calls to suitably equipped remote sites, for example another Vigor2800V router, to any other compatible VoIP device or, via a PSTN gateway to or from any other regular phone line or mobile phone worldwide.

Using the Voice-over-IP facility is simple. You connect any standard telephone (corded or cordless) to one of the phone ports on the Vigor2800V. Although you can dial IP addresses, you would normally dial someone's 'SIP Address' which they obtain from their SIP Registrar (such as DrayTEL). You hear ringing and bust signals just like on a normal phone line. The voice calls (speech) are digitised and compressed in real time to make maximum use of the bandwidth and DrayTek's high performance 'codecs' provide 'toll quality' voice calls (quality similar to a regular fixed telephone line). A preset QoS system automatically gives voice traffic priority over other traffic without your available bandwidth.
