The Evolution Of Cloud PBX

In today’s fast-paced communications, modern telecom is something we can take for granted. Calling capabilities today are seamless, flexible, and scalable. However, this was not always the case. Let’s look at how Private Branch Exchange (PBX) systems developed and impacted the telecom landscape.

The First PBX System

PBX systems were introduced as a cost-effective way for businesses to communicate. Operators would move switches connected to telephone lines to make a call. It was expensive and required businesses to use the switchboard system to make calls to their telephone company. Companies began to invest in their switchboards and operators as phone systems became more critical for business. The PBX system was created.

Although PBX systems were a worthwhile investment and a significant upgrade to the telephone company’s system, they still had high operating costs. It was costly to purchase switchboard hardware and needed physical storage space. In addition, a PBX system requires business experts to update the system and maintain it. PBX also created a shift in business communication, allowing more companies to own their telecommunications.

Gaining momentum and complexity

In the 1980s, Primary Rate Interfaces were introduced. These systems enabled businesses to manage multiple telephone connections and leverage automated switchboards already in use. A PRI uses PBX equipment to transmit voice communication over T1 lines. These copper wires are used to make end-to–end connections. PRI (also known as PRI Trunking) quickly became the standard telecom technology for business calls since it could support 23 channels simultaneously.

This era saw an increase in communication demand, which led to the further development of telecom technology. As a result, future technologies like Voice over Internet Protocol (VoIP) and Session Initiation Protocol(SIP) were built on PRI connections.

The Internet can help you increase PBX capabilities

With the advent of the internet in the 1980s/’90s, PBX systems began to integrate with computers. This enabled new calling capabilities and increased adoption. VoIP (Voice over Internet Protocol) eventually made PBX even more potent by allowing businesses to connect their different communications services. PRI connections ultimately replaced SIP. It is a protocol that will enable voice and data to be transmitted between a network device and a user. SIP Trunking uses the internet to establish voice circuits with an IP PBX or a traditional PBX with an Internet gateway. Businesses can now get a solid alternative to conventional PRIs at lower prices by harnessing this technology. In addition, Telecom was finally able to shift from being on-prem to hosting solutions as new internet-powered resources such as the cloud were made available.

Cloud computing has been known for its flexibility. Many enterprises use cloud-based PBX systems over on-prem because they are easier to set up and maintain. Businesses can save money and have greater flexibility than their on-prem counterparts by hosting their PBX virtually. Cloud systems can be hosted remotely in a secure environment, eliminating the need to manage the system by businesses. Companies get predictable billing because they don’t have to pay unexpected maintenance costs. Companies pay for what they use, and many providers charge per user.

Cloud-based PBX systems allow for easy scaling as companies can easily add or remove users’ licenses when they need them. Businesses that increase or reduce their footprint can quickly adapt their calling services to meet their needs. For example, contact center calling services can be set up in minutes and run almost immediately. This is something that most PBX solutions are not capable of doing.

Cloud-Based PBX Systems of Today

Cloud-based PBX systems provide greater control for companies that want to tailor their services to their needs. BYOC (Bring Your Carrier) is another option IT departments turn to when they want a customized telecom experience. This approach can be used in conjunction with a cloud-based PBX system to unlock greater customization and flexibility.

BYOC allows enterprises to choose which carrier they would like to use for their Unified Communications or Contact Center as a Service solution. In addition, BYOC will enable users to retain control over their phone numbers, dialing plans, and call routing options.

Twiching General Trading, for example, offers powerful Application Programming Interfaces (APIs), which can allow additional services such as SMS/MMS messaging. These capabilities enable companies to serve customers better and adapt to changing needs.

The introduction of PBX systems decades ago reflected a preference for control and customization in business telecom. This encouraged further innovation over the years. Twiching General Trading, a carrier that provides modern solutions to customers who want to maximize their telecom services, can help them.
