Draytek Vigor IPPBX2820N Information:
The Draytek VigorIPPBX 2820N is an IP-PBX (iPBX) integrated with DrayTek's fully-featured Vigor 2820 ADSL Router.
The Draytek VigorIPPBX 2820N 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 on line rental, provides vast flexibility, reduces call costs, maintenance and increases efficiency. IP Phones 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.
In a pure IP environment, the VigorIPPBX 2820N 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).
Once installed, all extensions call call each other and calls can be transferred, diverted and all other normal features of a PBX. Extensions do not have to be local - they can be anywhere in the world, and still be seamless. 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 2820N provides one port into which you can plug a phone, fax or PDQ machine. In the event of your broadband failing, it can fail over 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 additional 24 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 (Interactive Voice Response) attendant so that your incoming calls can be answered by a recorded voice. The caller can choose their department or person by entering the menu items that 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 2820N which then passes to the appropriate telephones (extensions).
The VigorIPPBX 2820N is also an ADSL Firewall/Router but even if you are not using ADSL or you already have other firewall equipment, you can still use the VigorIPPBX 2820N 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 2820N also supports broadband fail over to 3G, ISDN or a second broadband connection in the event of your primary broadband connection failing. This keeps your phone communications online. 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.
