What is an on-site phone system?

An On-site phone system, also known as an on-premise phone system or a traditional phone system, is essentially a phone system that is hosted and stored directly in your office and connects to copper Analogue or ISDN lines or SIP trunking which is internet phones lines although not all onsite phone systems support SIP trunking.

Although modern phone systems are all hosted in the cloud, there are still a lot of businesses that are better candidates for an onsite phone system such as businesses with extra security requirements that do not want their data potentially breached by a cloud server, having an onsite phone system allows you to have more control over this.

"Pleasant and Professional"

We have been extremely happy with the service from Intouch Communications. We thought changing our phone system was going to be such a headache, but they made the purchase and installation of our CallFlight 3CX telephone system a very pleasant experience and were professional throughout.

Features and benefits

On-site phone system pricing is structured around a high capital outlay with a low monthly rental. With on-premise phone systems, you do not pay per extension but rather pay for the number of telephone lines required across the whole system and the cost to support and maintain the system.

Intouch Communications have plenty of phone system customers and can advise whether or not an onsite phone system is best or if a Cloud Phone System solution would be better.

On-Site Phone System FAQs

Onsite or on-premise PBX (private branch exchange) refers to a system where hardware such as desk sets and computer equipment resides at your office. With an IP-PBX, the IP routing is done with more current technology, but the hardware remains on premises.
