The Internet Protocol (IP) defines how voice signals travel over the network. It’s used to connect telephones, pagers and other business systems like faxes, video conferencing and instant messaging. IP telephony, also known as VoIP, has revolutionized the way that businesses communicate. It has allowed business phone solutions to incorporate a variety of capabilities that help increase productivity, such as unified communications (UC) solutions that integrate a company’s telephone, chat, video and collaboration tools on one platform that can be managed over the same network.
What Is the Difference Between PBX and SIP Trunking?
While it’s true that IP telephony is a part of UC, the terms are often used interchangeably. The main distinction is that PBX refers to the telecommunication hardware, while SIP trunking refers to the underlying communication infrastructure that supports a VoIP system.
With SIP trunking, call traffic is delivered over the Internet or private data networks, instead of over traditional copper wires. This makes calls cheaper and provides more features than a traditional phone system.
As an IP-based solution, SIP trunking relies on a high-speed internet connection to work. Ideally, this needs to be a wired broadband service.
Because the system is dependent on an Internet connection, it can be disrupted if the service provider experiences any issues with their network. Therefore, the best way to ensure uninterrupted telephony is to partner with an Internet service provider that offers redundancy and has security measures in place.
