What is on-premise PBX?

An on-premise phone system (also known as on-premise PBX or hybrid PBX) enables the use of both traditional phone lines and the internet interchangeably to make and receive calls. This is a great option for anyone who doesn’t want to fully move over to “the cloud”. On-premise automatically uses the best connection at the time, helping ensure that your call quality is always at its best.
On-premise PBX is reliable and secure. It is installed on your business’s own servers and firewall, allowing you to manage your own data security and giving you peace of mind.

Are you looking for more flexibility? Check out our cloud phone systems, which can be used on a combination of mobile, desktop and tablet.

Our on-premise phone systems give you the best of both worlds. These systems have sufficient capacity for legacy and IP ports, therefore, you can utilise traditional telephone lines (analogue, digital) as well as SIP (VoIP) lines. Giving you crystal clear communications that suit any budget.

What is SIP Trunking?

A SIP trunk can be used in conjunction with an on-premise PBX system and allows you to limit the number of users on calls at any one time. We have found that industries, such as hospitality and schools, benefit from SIP trunking, as they do not require all users to be on the phone at the same time. For premises, such as call centres, an on-premise system with no SIP trunk or a cloud phone system would be the best option.
