Vigor 2100V Wireless Broadband Router with Voice over IP
The DrayTek Vigor 2100V is a broadband firewall/router - ideal for sharing
your Cable Modem between several PCs, with a built-in VoIP (Voice over
IP) telephone port. Even if you have just one PC, the router provides
the firewall facilities. The phone port enables you to use your existing
broadband connection to make VoIP calls to any other compatible device,
anywhere in the world and anywhere on the Internet, free of charge. You
can receive calls too of course, and all with a standard (analogue) telephone
which you connect into the socket on the back of the router.
Having the Vigor2100V on your broadband connection effectively gives
you an extra phone line - with no extra line rental, so when family or
co-workers are tying up the main line you can still make calls using the
phone on your Vigor2100V - ideal for teleworkers who need that extra flexibility.
The Vigor2100V is visually pleasing too; its curved lines and brushed
silver finish enable it to fit into any environment stylishly.
Automatic QoS Assurance
Traffic levels from your local users to the Internet can vary; if someone
else on your router is downloading, that will affect your speeds. Mostly
that's quite tolerable - you just get your data a little slower but you
wouldn't normally notice. With VoIP, things are different. A voice call
has to be digitised, transmitted to the remote end and the turned back
into an analogue waveform (sound!) in real-time. If part of a packet is
delayed then the sound becomes jerky and intermittent which at best is
annoying and in worst cases intolerable. The Vigor2100V firstly uses efficient
codecs designed to make the best use of available bandwidth, but secondly
includes automatic QoS Assurance. QoS (Quality of Service) Assurance reserves
part of your Internet bandwidth for voice calls whilst a voice call is
active (the reserved bandwidth is available for regular use if there is
no Voice call active). This means that, regardless of what else other
people are doing on your Network, you will always have the necessary inbound
and outbound bandwidth reserved exclusively for Voice.
Voice Over IP
Using VoIP is simple. You connect any standard telephone to one of the
two phone ports on the unit. In the simplest usage mode, you lift the
handset and dial the IP address of the remote unit ( * is used in place
of the normal dot). The router then contacts the remote router and the
phone connected at the other site then rings. The remote user lifts his
handset to answer the call and the two parties can then talk to each other.
More conveniently, you use the phone book to dial remote users with a
short code and a SIP registar/proxy to locate users automatically without
needing to know their IP address.
