On-Premise PBX

The perfect solution for remote offices with large workforces where Internet connectivity is not as strong as city areas.

For the ultimate in control and quality of service, you should consider an On-premise PBX.

An On-premise PBX system gives you long-term cost savings in operation, the ability to fully administer your own phone system and a smaller attack surface than a multi-tenanted Hosted PBX.

It’s a great solution for remote offices with large workforces (like mine sites) where Internet connectivity is not as strong as city areas.

Key On-premise PBX Features

Long-term cost benefits

Once the server that drives your phone system is paid down, the monthly operating costs drop significantly, making this a good long-term investment.

Best solution for remote sites

Remote sites with large workforces will typically see better results with more cost-efficiencies with an IP PBX.

Intra-office video second-to-none

In an On-prem PBX the video signal travels a shorter distance to the on-premises server to facilitate video conferencing. Very useful if you have a multi-floor office and need frequent face-to-face video conferencing.

Ultimate control

Keep your communication more private and tweak the settings to enable full customisation of features to your requirements with an On-premises PBX.
