What once began with switchboard operators running company switchboards by hand, led to large-scale integrated circuits and key systems that allowed business telephone systems to have their own individual lines for each connected phone. However, it was not until early electronic key systems were opted for that hybrid key telephone sets or alternative phone systems like a private branch exchange (PBX (News - Alert)) became the norm; since then, there has been a strong market for physical PBXs.
At first, the PBX used analog technology for phone communication; then it came apt for both voice and digital data transmission.
When the traditional Time Division Multiplexing (TDM) based PBX market fell, premises equipment and telephone switching became almost obsolete - due to the growth of the Internet, which led to the development of the IP-PBX and hosted PBX. This technology development reflected the growing need for diverse applications that support BYOD (Bring Your Own Device) over the IP (Internet protocol) to carry calls or data.
The 21st century has seen enterprises interested in Internet telephony for VoIP and messaging services hosted over the Internet.
Instead of buying PBX equipment and depending on the telephone company to provide voice and data phone services, organizations chose a hosted PBX system provider to control PBX phone functions over a Public Switched Telephone Network (PSTN) or the Internet.
Many of them, in fact, turned to third-party telecommunications providers to be responsible for the business phone system equipment and the connection of the infrastructure to handle telephone features such as call routing or switching.
In essence, Internet telephony – which involves integrating telephone services into a computer network – has simplified sending, receiving and forwarding data or callsas it offers the flexibility and scalability that has come to meet the needs of a business telephone system. In addition, it can help reduce long distance calling expenses while providing greater mobility and increased redundancy.
CommLogik, a distributor of services for Unified Communications (News - Alert) (UC) solutions for IP (data-packet) based end-point phone devices, has shared 10 benefits of an Internet telephony PBX system; it indicated reasons why transitioning from a legacy PBX to an IP-PBX business phone system is the right telephone solution for everyone, from carriers to end-users.
Switching to an IP-PBX and using a VoIP provider's proprietary app can help reduce communication and infrastructure costs for telephone calls over the Internet that are long-distance or international. IP-PBXs also utilize a complete computer-based system – integrating phone functions with business applications – which can deliver improved customer service and productivity for SMBs. Also, an IP-PBX based on a data network offers an innovative approach to implement a scalable business phone system and, a hosted cloud-based IP-PBX phone system can handle all SMBs’ voice and data needs.
The software which enables IP-PBXfunctionality --to ensure all the benefits of computer telephony integration (CTI (News - Alert)) to deliver voice or video over a data network-- is easy to install, configure and customize.
Through the user friendly Windows GUI, the IP-PBX can offer conference calling, call forwarding and transfer. The system includes interconnecting wiring for the key system hardware equipment to easily be set up and installed. The device connects via a network port where the software makes it possible to perform call-routing or any other phone function.
With many of today’s IP-PBXs supporting SIP (Session Initiation Protocol (News - Alert)) phones and SIP routing as well as more service providers being on board with deployment of the SIP infrastructure, no longer are businesses locked in to only one IP -BX vendor to achieve basic interconnection between SIP-enabled IP-PBX systems over a PSTN Gateway (News - Alert) or service provider’s VoIP-enabled network.
