VigorIPPBX 2820 - Integrated IP-PBX & ADSL Firewall

The VigorIPPBX 2820 is an IP PBX integrated with DrayTek's fully-featured Vigor 2820 ADSL Router.

The VigorIPPBX 2820 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. IP Phones (such as the VigorPhone 350) can be placed anywhere in your office, or remotely around the world to provide one seamless phone network for your business. Wherever you have an Internet connection, you can have an extension on your PBX. All pure IP calls are free of charge; for calls to the conventional phone network (PSTN) you route via an ITSP 'Trunk' for low cost calls (for example DrayTEL).

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 into which you can plug a phone, fax or PDQ machine and in the event of your broadband failing, it can failover onto your regular analogue line. That analogue phone is then another extension on the PBX, able to receive, transfer and make calls. You can add an 24 additional analogue extensions with the DrayTek VigorTalk 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.

Voicemail can be enabled on any extensions to take messages when the phone is not answered or busy. 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 also use it to provide automated information such as opening hours or travel directions.

For calls to and from 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 routes 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).

IP PBX using a SIP Trunk such as DrayTEL

The VigorIPPBX 2820 is also an ADSL Firewall/Router (see regular Vigor 2820 for full router features) but even if you are not using ADSL or you already have other firewall equipment, 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 existing WAN connection, instead of using the ADSL port.

The Vigor IPPBX also supports broadband failover to 3G, ISDN or a second broadband connection in the event of your primary broadband connection failing. This keeps your phone communications online. The diagram shows the primary ADSL line with alternative failover connectivity of ISDN or 3G or a secondary ADSL line:

IP PBX with ADSL Failover or Backup

Also by the use of a secondary Internet access method, you can set up Load Balancing whereby speciifc traffic types are routed down one particular connection. This is the optimum configuration for the very best quality, where your Voice traffic can be sent down one connection and your regular web traffic send down the other:

IP PBX Load Balancing



Extensions & Groups

The VigorIPBX 2820 supports up to 30 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 can have their own voicemail (answerphone) preferences, for example sending a caller to voicemail when you're on another call or don't answer. 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 VigorPhone 350, 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 (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).

VigorPhone and VigorSwitch

VigorPhone 350 and VigorSwitch P2260

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

Vigor 2820 in RM1 Rack mounting bracket

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

VigorTalk ATA-24SH

The VigorTalk ATA-24SH provides 24 analogue phone ports (FXS) for your Vigor IPPBX so that you can connect up to 24 regular phones, cordless phone bases or other analogue equipment to your IPPBX.


Wireless LAN ('VigorIPPBX 2820 n' model only)

The VigorIPPBX 2820n features 802.11n wireless LAN specification and has been certified by the WiFi alliance for cross compatibility and WiFi compliance (including WPA/WPA2 and WMM).

802.11n provides a total wireless bandwidth of up to 300Mb/s using new methods such as packet aggregation and channel bonding. Throughput depends on your own environment (factors such as obstructions, number of hosts and distance all make a significant difference), but actual transfer speeds of 100Mb/s are achievable (based on our real world tests). In addition, 802.11n provides greater coverage and resilience to interference compared to previous wireless standards thanks to the MIMO technology and the Vigor's triple-antennae diversity arrangement. This offset arrangement of aerials provides offset paths between hosts so that interference can be overcome.

Wireless Security is comprehensive too; the VigorIPPBX 2820n provides several independent levels of security including encryption (up to WPA2), authentication (802.11x) and methods such as MAC address locking and DHCP fixing to restrict access to authorised users only. The Web interface lets you see how many and which clients are currently connected as well as their current bandwidth usage. An 'instant' block lets you disconnect a wireless user temporarily in case of query. The Wireless VLAN facility allows you to isolate wireless clients from each other or from the 'wired' LAN.

The Multiple SSID features enables you to have up to four distinct or common virtual wireless access points. For example, you could have one for company usage, with access to your company LAN and another for public access which allows internet surfing only. Setting up wireless security is made easier thanks to the WPS feature (WiFi protected setup) whereby your client PC can get it's security keys by pressing a button on the front of the router.

If your laptop PC's built-in wireless doesn't support 802.11n Draft 2.0 wireless, you can use the optional Vigor N61 USB adaptor. Click on 'accessories' for details.

For specialist or more demanding coverage applications, optional aerials can be used with the VigorIPPBX 2820n to potentially increase the range of wireless coverage (depending on enviroment) or provide directional coverage in order that your wireless transmission is focussed and concentrated into one direction only, for example into a room or across open space. With the increasing popularity of wireless LANs, you will want to choose the least congested wireless channel (Nos. 1-13) for yours. The Vigor can scan and provide a list of all devices in the vicinity so that you can choose the best channel (see screenshot below).

Wireless LAN WDS Facility

VigorIPPBX 2820n model supports WDS (Wireless Distribution System) which enables you to use the wireless capability to bridge to another network, within wireless range. You need an additional compatible wireless router for this of course. Here is a simple example:

DrayTek Vigor Wireless LAN WDS Bridiging

With WDS bridging, both networks should be within the same logical IP subnet (IP address range). Once set up, all of the PCs on both sides of the link can access each other, across the wireless bridge. Local wireless devices such as a laptop can continue to use their local access point.

VigorIPPPBX 2820n WDS Repeater

An additional mode, as shown above, called 'repeating', allows you to set up a third station. In the diagram below, the router at 'B' is set up in repeating mode, relaying traffic between LANs at A and C. Therefore, all three physical networks can communicate with each other over the wireless links.

Important Note : Wireless performance (speed and range) always depends on your specific environment and will vary considerably. Factors affecting performance include wireless traffic, other networks nearby, site construction, walls, ceilings and other electronic equipment nearby. The product may not be upgradable to future 802.11n draft standards or be compatible with products from other manufacturers. Speeds quoted are the maximum wireless capacity, including RX/TX capacity, protocol overheads and all clients/hosts connected.
