On Premise Telephone Systems
Trusted Expertise in On-Site Telephony
While many organisations are moving to hosted and cloud-based solutions, on-premise telephone systems remain the right choice for some businesses. Mainstream continues to support and deploy on-site telephone systems for customers who require greater control, specific integrations, or a phased approach to modernisation.
Our experienced engineering team has decades of hands-on experience designing, installing, and supporting on-premise telephone systems across a wide range of industries. This depth of expertise allows us to deliver robust, reliable solutions tailored to the unique operational requirements of each customer.
Proven Technology Platforms
We have extensive knowledge of leading on-premise telephony manufacturers, including:
NEC
Samsung
Panasonic
These platforms are well established in business environments and continue to provide dependable voice communications for many organisations.
New on premise systems are implemented using 3CX platforms, as we have long term control of the hardware platform and a clear upgrade path through the 3CX Roadmap.
Ongoing Support and Future Planning
In addition to installation and maintenance, we support businesses in extending the life of their existing systems, integrating them with SIP and Unified Communications services, or planning a smooth transition to hosted solutions when the time is right.
