The Internet Only Solution
Scenario: You wish to operate a large organisation but
to use the cheaper and more flexible voice over internet over a single
internet connection:
As a Firewall/Router, the VigorIPPBX 3510 phone system
provides renowned security and flexibility for your network's Internet
connectivity, together with the backup and performance your require in a
large organisation.
In a pure IP environment, the
VigorIPPBX 3510
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 3510 PBX can support up
to 100 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 3510 can be expanded with
optional modules or if you need even more, 24 analogue phone 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. You can also integrate the PBX with
existing analogue phone lines with optional plug-in modules. See the
section on modules for more information.

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).

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 sl ouse it to provide common information such as opening hours or
location details.
