Overview

VigorIPPBX 2820- Integrated IP-PBX & ADSL Firewall The VigorIPPBX 2820 is an IP-PBX (iPBX) integrated with DrayTek's fully-featured Vigor 2820 ADSL Router. It offers a complete replacement to the traditional office phone system and analogue or ISDN lines. An IP-PBX uses your existing network and the Internet to provide company-wide telephony, using VoIP technology instead of regular phone lines or a traditional PBX. This can save hugely on line rental, provides vast flexibility, reduces call costs, maintenance and increases efficiency. Phones can be placed anywhere in your office, or around the world to provide one seamless phone network for your business.

In a pure IP environment, the VigorIPPBX 2820 is installed onto your LAN together with IP telephones, such as the VigorPhone 350. All devices are connected over your LAN using your existing Ethernet network connections. The Vigor 2820 PBX can support up to 50 extensions - local or remote. As it uses your regular network, you don't need special extension wiring - just your existing Ethernet switch with adequate ports (assuming you are using IP phones). A traditional PBX with 50 extensions would take up a whole cabinet and need a lot of wiring! Once installed, all extensions call call each other of course and calls can be transferred, diverted and all other normal features of a PBX. Extensions do not have to be local (in the same office as the iPBX) - they can be anywhere in the world, and still be seamless so that calls can be made between to transferred to extensions whether they are local or remote. Similarly, incoming calls can be routed to any extensions, whether they are local or distributed in many remote locations - anywhere with an Internet connection.

If you require analogue extensions (regular non-IP telephones or equipment) then the VigorIPPBX 2820 provides one port but you can add 24 additional analogue extensions with the DrayTek ATA-24SH. Analogue extensions are useful for legacy equipment, lower cost extensions or where you don't want the risk of loss or damage to an IP phone.

For the connection to the regular PSTN - the public telephone network, you need an ITSP (Internet Telephone Service Provider) who can provide you with a 'SIP Trunk', such as DrayTEL. Then, when your users need to make an external call, the iPBX can route automatically via the ITSP gateway on the Internet. The ITSP will also provide you with incoming phone numbers to receive calls. Those calls are routed into your VigorIPPBX 2820 which then passes to the appropriate telephones (extensions). The VigorIPPBX 2820 is also an ADSL Firewall/Router but even if you are not using ADSL or you already have other firewall arrangements, you can still use the VigorIPPBX 2820 for your VoIP telephony; the unit's second WAN port is standard Ethernet which can connect into your WAN connection, instead of using the ADSL port.

Voicemail can be enabled on any extensions to take messages when the phone is not answered or busy and the message can be emailed to the extension owner, or they can pick it up from their phone when they return. Other features include an IVR (Automated Voice Response) attendant so that your incoming calls can be answered by a recorded voice and the caller can choose their department or person by entering the menu items you have set up (e.g. press '2' for sales). You can aslo use it to provide common information such as opening hours or location details.

Schematics

PBX History

To understand exactly what a 'PBX' is, it is useful to know a little bit about the history of them.

A 'PBX' was traditionally called a 'switchboard'. The earliest switchboards in companies (or hotels, hostpitals etc.) used an operator (almost always a woman). The operator would physically connect the jack of one extension to the socket of another extension, or to an outside line (the PSTN). See the image on the right to see how that looked. This was a PMBX - a Private Manual Branch Exchange. Exactly the same system was used at public telephone exchanges - think of old films where someone picks up the telephone receiver and says "Operator, get me Kansas 5321!". Later the Automatic Exchange (electromechanical) together with the rotary dial telephone was invented; this allowed phone users to dial a destination phone number themselves and the call to be routed automatically without the assistance of an operator. Within a company, this was a PABX or PBX (Private Automatic Branch Exchange). In these systems, every phone call was passed between the two parties and across the public network on a physical pair or wires. With Voice-over-IP, you'll know that your voice and the dialling information is all transferred digitally across your network and the Internet, however the concept of a switchboard (exchange) is still vital. It is still the job of an exchange to keep track of subscribers (location and status) and route calls to and from them. Of course, as PBXs (and public exchanges) developed, many additional services were introduced, such as caller ID, call diversion and call waiting - all of these are managed and operated by the exchange/PBX. In summary, a PBX (whether IP, ISDN or analogue, can perform the following: Monitor the Status of a subscriber (busy, absent, free) Time and log all calls made (for statistical or billing purposes) Take voicemail (answerphone) messages in case of busy/no-answer Store the voicemail for telephone retrieval or forward the message by email Route calls from extensions appropriately (to the right destination or interface) Accept incoming calls and pass them to the appropriate extension Transfer calls between extensions Conference Calls Call Waiting Caller ID

Extensions

Extensions & Groups

The VigorIPBX 2820 supports up to 50 active extensions. Each extension will be used for an IP desk phone (such as the VigorPhone 350, shown on the right), an analogue extension (either built into the IPPBX, on the ATA-24 device or some other analogue adaptor) or some other SIP-compatible VoIP device. The extensions can be on the same LAN as the IPPBX in your office or remote, in another office or someone's home. All extensions can call each other and transfer calls between each other. Extensions can also be part of a group, so that calling the 'group' number will call all extensions who are members of the group. This is ideal for departmental usage, for example you can put a call through to the 'sales department' group and all of their phones will ring, so anyone in that department can answer the call. Individual extensions all have their own voicemail (answerphone) facility. You can record your own message and then callers' messages can be listened to when you return to the office, or emailed to you wherever you might be. Using a phone like the VigorPhone350, the MWI (Message Waiting Indicator) light flashes so you can tell when there is a message waiting. You can also set your extension to divert to another extension or group if not answered within a certain time.

Auto-Attendant

Auto-Attendant (IVR)

The Auto-Attendant can answer your incoming calls and direct your caller to the correct department without any operator/receptionist intervention. You can record your own messages and set up the destinations of each selection, whether it's a group, individual extension or even a remote user. The caller can also dial extensions directly if they know the person's extension number. If the caller's selected department or person is busy, they can be put through to voicemail or placed in a queue, awaiting the next available person in that group. The auto-attendant can also be used to give out frequently requested information such as your address, opening hours or travel directions, saving your staff much time from this repetitive task. For out of hours periods, a different message can be automatcially played, perhaps telling the caller of your opening hours and alternative numbers to call or other resources available in the meantime (for example web addresses).

Accessories

VigorPhone and VigorSwitch

The DrayTek VigorPhone 350 is an IP Telephone designed specifically for use with the Vigor2820PBX (it will work with other IP PBXs and SIP servers too). The VigorPhone 350 supports PoE (Power over Ethernet)so when used with a PoE Ethernet switch, such as the DrayTek VigorSwitch P2260 (also shown) no power supply is needed, cutting down on wiring clutter around the desk.

Rack Mounting Kit

The RM1 Rackmount Bracket enables you to fit any Vigor 2820 series router into a standard 19" rack or cabinet. The bracket takes up one rack slot (1U). The front mounted sockets remain fully accessible.

24-Port Analogue Phone Adaptor
