10 Reasons why you should choose an IP Telephone System over a conventional legacy system


The Sustainable PBX Solution.

  • Portable
  • Flexible
  • Redundant prof . .

The ULTIMATE reason is that it’s Sustainable where as conventional Copper Based communications media as almost at it’s “End Of Life” (EOL).

Major Telecom’s companies are shutting down their PSTN and ISDN networks and migrating to SIP / VoIP telephony through the implementation of  layer 4 soft-switching across public data networks.

Therefore, within the very near future IP Telephony will be your “Only Alternative”.

IP Telephony systems also provide many “Portability and Redundancy” proofing options.

It can be run across the NBN, ADSL, Cable internet, Cellular Networks, Mobile broadband services like 3G, 4G 5G and satellite links. It can even be used on wireless networks like food halls and shopping malls.


What is an IP PBX Telephone System?

A Private Branch Exchange (PBX) is a multi-line business telephone system that serves an organisation by concentrating central office lines into trunks and provides intercommunication between large numbers of telephone extensions within the organisation.

The central office lines or trunk provides connectivity to the public switched telephone network while the trunking feature of a PBX permits the shared use of these lines between all extensions within the organisation. The intercommunication function allows two or more stations to establish telephone or conferencing calls between them without using the central office equipment.

Each PBX-connected endpoint such as a telephone handset or fax machine is often referred to as an extension and has a designated extension number that may or may not be mapped automatically to the numbering plan of the organisations office and the telephone number block ( direct in-dial numbers) allocated to the trunk.

The primary advantage of a PBX is the cost savings for internal phone calls: handling the circuit switching locally reduces charges for telephone service via the central trunk. PBX systems are equipped with services that are not available in the public network, such as hunt groups, call forwarding, and extension dialling, call conferencing, queues, night switches, auto attendant and follow-me always.

A PBX selects the outgoing line automatically and employs an organisational numbering plan for its stations. A  dial plan determines whether additional digits must prefix a number when dialling to obtain access to an office trunk. Modern number analysis technology permits users to dial internal and external telephone numbers without special codes to distinguish the desired destination.


How does it work?

IP PBX Systems integrate into the Local Area Network (LAN)

An IP PBX Telephone System incorporates SIP phones, a communications server and a Gateway such as VoIP, PSTN or ISDN to make calls across  the local or mobile telephone network.

The communications server or IP PBX functions like a proxy server ie. The SIP end-points, being a soft phone or hardware-based phone, registers to the SIP server (IP PBX System) which establishes the connection when the number is dialled through the gateway  of choice.

The SIP Server maintains a directory of all telephone extensions and their corresponding IP address which enable it to connect to an internal or external route.


Benefit 1: An IP PBX system is far easier to install than a traditional telephone system:

An IP PBX or SIP server runs like a computer using IP addresses to connect to your Local Area Network (LAN). Anyone with a basic knowledge of IP networking can install a IP PBX. By comparison a traditional phone system requires an installer trained specifically for that particular proprietary system!


Benefit 2: It’s easier to manage through the web based interface:

An IP PBX System can be managed via a web-based interface called a GUI, making it easy to maintain and manage your phone system. Traditional telephone systems are cumbersome to configure using codes and scripts to interface with call routes, queues, auto attendants and  hunt groups etc. which are intended for use only by phone certified technicians.


Benefit 3: Eliminate the need for cable installation:

As IP Telephone systems reside on the Local Area Network (LAN)  using IP Protocols and connects IP phones directly across the computer network it eliminates the need for phone wiring and makes adding or moving an extension much easier. In new offices the standard data cabling eliminates the need for extra ports for office phones!


Benefit 4: There are significant cost savings by using VoIP:

With an IP PBX System you can use an Internet Telephone Service Provider (ITSP) –  Voice over Internet Protocol (VoIP) provider for local, long distance and international calls. The call charges are less and savings are significant. If you have branch offices, nationally or internationally, you can daisy-chain IP PBX systems between the branches and make free telephone calls.


Benefit 5: IP PBX Systems are scalable:

Traditional telephone systems are easily outgrown. Adding more phone lines or extensions often requires expensive add-on modules. In some cases you need replace the entire telephone system. An IP PBX can easily accommodate a large number of phone lines (channels) and extensions. Simply add more phones to your network and your done.


Benefit 6: Streamlined your workflow and productivity:

IP PBX systems deliver better customer service and productivity by integrating telephony functions with business applications.

Some examples are;

  • Presenting customer details about the caller automatically when the call is received.
  • Save money by reducing time spent on each caller.
  • Outbound calls can be placed directly from Outlook or the integrated “Customer Relationship Management” software (CRM), just click to dial.
  • Web Conferencing. Share documents during a presentation in a teleconference.
  • Conference Rooms. Host large teleconferences fro your own system.
  • Telemarketing. Use the Predictive Dialler feature to call your entire customer database without dialling a single number.
  • Hotel Rooms and Hospitality. Automated Management and Billing systems.
  • Surveillance Systems. Capture, record and analyse video data and monitor cameras in real-time.


Benefit 7: Avoid being locked-in to a vendor:

All IP PBX systems are based on open source SIP standards. This technology empowers the user with cross platform compatibility, making it possible to combine any SIP compliant, IP based hardware or software phone with any SIP-based IP PBX system, PSTN / ISDN Gateway or VOIP provider. In comparison, a traditional telephone system often requires proprietary telephone handsets to use the advanced features, and proprietary expansion modules to add those features.


Benefit 8: More telephony features for less money

As IP PBX systems are software-based, we at iWolf are able to add and improve on many advanced features. Most IP telephone systems including auto attendant, voice mail, ring groups, advanced reporting and more. These options are usually very expensive in traditional systems. A full blown IP PBX system with all the bells and whistles will cost approximately one quarter of an equivalent traditional telephone system.


Benefit 9: SIP phones are User-friendly:

Many people often struggle using advanced telephony features. Initiating a conference call and transferring a call  often requires detailed instruction on a traditional PBX system. However, with an IP PBX System all functions are easily performed via the user friendly digital display. IP PBX Users experience an improved overview of the other extensions, inbound calls, call queues and auto attendants via the IP PBX systems web GUI. Traditional telephone systems often require expensive consoles to acquire a cryptic view of call traffic across the phone system.


Benefit 10: Flexible user locations. Hot Desking.

Hot Desking makes it possible for users to easily move offices desk locations as their job dictates while maintaining their internal extension number. With an iWolf IP PBX system the user simply sits at the new desk location without moving any hardware at all and enters their PIN into the nearest handset. That handset is now reassigned with their old extension number. Traditional PBXs require extensions to be re-patched or re-configured to the new location. Users can also roam if an employee chooses to work remotely by using a softphone application on their PC. This enables them to seamlessly answer calls from anywhere in the world that would normally go to their extension.


The Obvious Choice

In conclusion, investing in an iWolf IP PBX system is a total “No Brainer”, not only for established companies but also for new  businesses buying their first telephone system. iWolf IP PBX systems return such an enormous “Return On Investment” (ROI) and savings on maintenance, management and ongoing call costs that buying an iWolf PBX system  is the obvious choice for any business.

FYI. Regardless of size, the average iWolf PBX system pays for itself in savings within the first 8 to 10 months of use.
