System Support
Legacy PBX support from engineers who understand older systems

On-premise and hybrid support
Specialist support
Keeping critical business communications running
Whether you rely on Avaya, Mitel, Siemens HiPath, Siemens Unify, Nortel, NEC, Panasonic, Splicecom or Sangoma, Intuity can provide practical support, maintenance guidance and technical expertise to keep your communications estate operating effectively.
Legacy voice support
Support for systems that still play a vital role
Many organisations continue to rely on established PBX platforms because they remain business-critical, are integrated with wider workflows, or cannot yet be replaced without disruption. That is why legacy support still matters.
Intuity helps businesses keep those systems stable and operational with experienced in-house technical support, practical fault finding and a clear understanding of the wider voice and network environment.

End-of-life support
Manufacturer support ended? We can still help

In-house capability
Experienced engineers with deep PBX and voice knowledge
Supporting older systems takes more than basic helpdesk knowledge. Legacy PBX platforms often involve specialist cards, handsets, voicemail, call routing, SIP trunks, gateways, analogue lines, network dependencies and bespoke customer requirements.
Intuity has a highly skilled and fully certified team that understands the detail needed to keep these systems performing. We can support the PBX itself as well as the surrounding connectivity and infrastructure, helping identify the true source of issues and keeping disruption to a minimum.
This means customers gain a practical support partner that can stabilise today’s service while also helping shape tomorrow’s communications roadmap.
