VoIP PBX
VoIP PBX or IP PBX (Internet Protocol Private Branch Exchange) is a
telephony system that makes use of IP data networks to establish
telecommunications with the IP PBX server similar to a proxy server.

The
VoIP PBX is a telephone exchange contained within an
organization, or home, which is used to switch calls between internal
handsets and between internal and outside telephone lines.

The basic design of an IP PBX system consists of an IP PBX server,
one or more SIP phones or VoIP phones, and a
VoIP gateway, connecting
to the existing PSTN lines.

The immediate advantage of VoIP PBX is that you will not have to replace
your existing phones or phone numbers to accommodate a new VoIP facility.

The most important plus of VoIP PBX is that it is easier to install and configure
than a traditional phone system.

Another great feature you get when installing an Asterisk business VoIP PBX
is either music or company messages while your customer is in the call
queue.

The
SIP or VoIP phones, which can be either hardware phones or soft
phones, has to register with the IP PBX server, and when a call is made to
another phone a VoIP or SIP phone will actually make a request and send
it to the IP PBX server to establish the connection.

The IP PBX server will have a directory of all users/phones and their respective
SIP addresses, and using this info, it could connect an internal call or
route an external call via a VoIP service provider or a VoIP gateway,
whichever is applicable.

Anyone who knows the basics of computer and networking can install the
IP PBX in a PC.

Connect a
hardware phone to an IP PBX system by directly plugging it into
a standard network port (soft phones can be installed directly into the PC).

The big advantage of IP PBX is its low cost of operation.

IP PBX is built on an open
SIP standard, use any SIP software/hardware
phone with basically any SIP based
PSTN Gateway, IP PBX or VoIP provider.

With an
IP PBX system installed, you will be able to easily handle numerous
phone connections and extensions without effecting the efficiency of the network.
