The Preferred Phone System for many companies is an on-premise PBX
An
on premise PBX routinely turns out to be the best choice for many
businesses.
An on-premise PBX is where the phone system server
physically resides inside the establishment's property.
Companies looking to replace an older phone
system routinely maintain in place the appropriate infrastructure. This
includes their existing dial tone usually in the form of a number of
business phone lines (PSTN) or a T1/PRI (ISDN) from a local Telco.
Furthermore, some established businesses frequently retain a portion
of
older telephone wiring for phones where the expense to
upgrade cabling would be costly. Most often these phones
reside in locations such as warehouse space where phone use
is low. Companies that fall into this category regularly
determine an on premise
hybrid PBX is the best solution.
An on premise PBX has a Lower Cost over Time
Most VoIP providers offer plans that require a standard monthly
fee for each phone. In the case of a company with 150 phones the
ongoing monthly expense can quickly get excessive. At
$25.00/phone per month, the provider's service would be $3,750.00 for 150 phones
not including the cost for Internet. Alternatively, a company that uses a PRI at
$500.00/mo., which frequently includes twenty phone numbers
(DIDs) with a number of included minutes and Internet, dramatically
reduces expenses.
On premise PBX phone systems can easily be financed.
Using $3,250.00 as a monthly payment could pay off the entire on
premise project in roughly two years. Once the financing is paid off monthly
business expenses dramatically decrease.
Add SIP Trunks for additional Savings
For companies that produce a considerable amount of calls, especially
International, an on premise IP-PBX can use a few SIP trunks to take
advantage of low cost calling. SIP trunks are affordable and easy to
configure on most IP-PBX systems.
With a PRI
(Primary Rate Interface) you can dynamically send up to 23 separate
communications channels for voice, video or data. Great for medium
to large companies. The diagram shows a hybrid IP PBX that connects
both IP and digital phones to the dial tone provider through a PRI.
All signaling goes from the phone to the PBX, staying inside the
premise. When Bob in the warehouse dials an office phone the call is switched inside the companies' network.
Calls to and from the PSTN go in and out through the PRI. Each phone
can be assigned its own DID (Direct Inward Dialing) phone
number. That allows outside calls to go directly to an employee's phone
if desired.
More Control with an on-premise PBX
A
significant advantage for placing the PBX server in your facility is
you have absolute control over how features are configured and the network. It allows for
more customization including the ability to determine in house the
required level of security. The loss of Internet won't
necessarily take down making and receiving phone calls. You can keep
your phone calls separate from your Internet traffic. One drawback
of VoIP calls is that congested Internet traffic has an effect on
voice traffic. An on premise PBX incorporates signaling inside your
own network and offers crystal clear voice.
