The DrayTek Vigor 2100V is an broadband firewall/router - ideal for sharing your Cable Modem (e.g. VirginMedia, Telewest or NTL) between several PCs. The firewall helps protect your PCs and network from external hackers and other Internet attacks and the Vigor2100V is also compatible with your games consoles or other compatible devices. The Vigor 2100V's curved lines and brushed golden finish enable it to stylishly fit into any environment. |

The Vigor2100V provides a built-in VoIP (Voice over IP) telephone port. This 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.
By using the DrayTEL PSTN gateway (see later) you can also make calls to or from any regular phone line worldwide, including mobiles - the call is carried to/from your phone via your internet connection so your regular phone line remains free for other people/calls.
Having the Vigor 2100V 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 Vigor 2100V - ideal for teleworkers who need that extra flexibility.
In addition to the broadband connection, the Vigor 2100V connects to your regular analogue phone line so with just a single phone on your desk, you can choose to make calls using VoIP via the Internet or, by dialling #0 before the call, switch over to your POTS line and dial out via the PSTN (the conventional phone network - for example BT). Incoming calls can be received from either source too - either POTS or VoIP - the phone will ring on either. The Vigor 2100V features automatic failover, so in the event of power loss, the Vigor automatically switches your phone over to the POTS line so that you can still make/receive calls. Additionally, if you have a VoIP phone number (SIP Address) in the speed dial memory, you can also specify a backup phone number for each entry, so in the event of Internet loss, the router will automatically dial an alternative number via your regular telephone line. In normal use, you can tell which line you are using by the LED colour - green for VoIP and amber for POTS.

Security is important to Internet users, so the Vigor 2100V also provides firewall facilities. But default, your internal PCs are isolated from public access - this means that they can communicate outward, but external users cannot send to your PCs. Where communication is requested, a the router keeps reciprocal records (also known as 'keeping state') in order to know that data coming back is solicited and okay to pass back. In additional to these automatic systems, you can also set additional data filters to block specific packet types by protocol type or source or destination IP. Automatic anti-DoS (denial of service) code also help protect further against malicious attacks. It is still recommended that you always run anti-virus software on your PCs to allow for trojans and other virus threats coming from inside your network.
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.
| If your ISP (or other email provider) uses the POP3 protocol for their mail server, then you can set your router to periodically check for email, and the LED will light if there is email waiting for you (see right). You can have up to five different POP3 accounts checked. This means that you can see if there is email waiting without having to turn on or log into your PC. |  |
| Calls between VoIP users can be made simply by dialling each other's IP addresses, but as IP addresses are long and can change, a SIP registrar (such as DrayTEL) can allocate you a more convenient ID for people to call you on. A SIP ID/address, for example, might be 899899@draytel.org. Then other SIP users can call you on your DrayTEL address (normally even if they don't use DrayTEL themselves). |  |
| The DrayTEL server also provides another important facility - a gateway to the PSTN. This means that using your Vigor2100V, you can not only free make calls to other VoIP/SIP users, but you can call any regular telephone line or mobile phone too (calls to the PSTN are chargeable at attractive DrayTEL rates). DrayTEL can also allocate your own personal '0870' (national rate) phone number for anyone to call you on. | |
| With your router you'll receive a voucher entitling to a free DrayTEL account, free allocation of a PSTN incoming phone number and £2.00 worth of call credit to make calls to regular phone lines worldwide (you can buy more credit). Remember call credit is only needed for calls to the PSTN - VoIP-to-VoIP calls are always free (so get your friends to buy a Vigor 2100V too!). There is no charge to you to receive calls from the PSTN via your DrayTEL PSTN number and there is no rental charge. Note : The DrayTEL service is operated independently of DrayTek Corp. and usage is subject to DrayTEL's own service terms. Voucher valid in UK/NI only | |
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. It's rare, however, that users do actually dial by IP address, particularly as most user's IP address changes regularly; services such as DrayTEL provide friendly 'phone numbers' to reach other users on, regardless of their current IP address.
Rather than having to type (dial) whole destination numbers each time, the Vigor 2100V has a quick-dial directory for up to 99 entries so that you can use a short code (of your choice) in place of a long IP address, as well as enabling you to store SIP registrry names or dynamic DNS names. The router will automatically keep the SIP registrar updated with your current location (by IP address) so you do not need a fixed IP address.
