What is PBX and SIP Trunking?

Even though telephone systems have been around for decades, technological advancements have caused considerable changes in recent years. As a result, business owners want to know what is PBX and what does it offer in today’s world?

PBX, or Private Branch Exchange, is a private telephone system used by businesses to route calls to the public switched telephone network (PSTN) and VoIP networks. The users of the PBX are assigned extensions. The extensions share a certain number of external phone lines. The main purpose of a PBX is to eliminate the need for every user to have a dedicated phone line.

Today’s PBXs provides sophisticated features, such as auto attendants, custom messages, voicemail to email transcription, follow-me services, conferencing and much more. PBX functionality provides many benefits for today’s mobile workforces and customer-centric corporate cultures.

On-Premise vs. Off-Premise, Traditional vs. IP-Based

The types of PBXs available today are distinguished by where they’re located and the underlying technology used to transmit calls. A PBX system housed at a company’s location is referred to as an “on-premise PBX.” A business maintains more control over an in-house PBX system. Because maintenance is handled internally, the company must staff qualified professionals with a high level of communications and IT expertise.

When a company uses an off-site or Hosted PBX, it shifts ownership of the system, and responsibility for managing it, to a service provider. The need to staff internal technical experts is eliminated or greatly reduced.

The transmission technology used within a PBX can be traditional analog (circuit-switched) or digital (IP-based). The latest development is the VoIP PBX, or IP PBX. A software-based system, the IP PBX uses Internet Protocol to transmit calls.

How Can Companies Access the Latest IP-Based PBX Technologies?

You can get the latest and most advanced features without buying a PBX system. You have two options: You can configure a SIP trunking solution for your on-premise system. Or, you can migrate to a Hosted PBX model. Both options provide unique advantages.

SIP trunking allows a company with a traditional, or legacy, on-premise PBX to access the latest features offered in an IP-based system. You accomplish this by connecting your premise-based PBX to a service provider’s softswitch network. Using SIP trunking, you can extend the life of your current system without having to invest in expensive PBX equipment upgrades.

Hosted PBX is a service where the call platform and PBX features are housed at a service provider’s facilities. Business users connect to the provider to access voice services.

Because Hosted PBX solutions offer so many advantages, they continue to grow in popularity. Some of the major benefits include:

  • Affordability – Hosted PBX eliminates large capital investments in expensive equipment. This solution provides advanced functionality and features for a low monthly recurring fee.
  • Maintenance Included – The service provider will handle set-up, installation and maintenance of the PBX system. You don’t need related communications experts on staff.
  • Worker Mobility – With a Hosted PBX, your employees can work from any location – at home, in the office or while traveling.
  • “Big Business” Features – Even small businesses can appear big with a Hosted PBX solution. Every business can access the same features Fortune 500 companies use.
  • Scalability – Unlike a traditional phone system, you will never outgrow your Hosted PBX solution. You can affordably expand your solution quickly and easily to meet current requirements.
  • Simplicity – With a Hosted PBX, you’re up and running quickly. The solution is user-friendly and requires no specialized skills or expertise.
