TSI work with you to provide efficient communications to meet your business needs.  From cloud based Unified Communications and video conferencing to enable seamless transition from working from home to working in the office, turning Microsoft Teams into your phone system, through to  superfast and reliable connectivity, we consult with you to provide the right solution for you.

With CallSwitch, our industry leading cloud unified communication solution you can receive a call to your business phone numbers wherever you are – in the office or working from home – and make calls using any device with free calls to landlines and mobiles*

CallSwitch future-proofs businesses against the PSTN switch-off in 2025, when all analogue and ISDN lines must be replaced with VoIP solutions.

Working remotely? With one-number you will never miss that important call again. Leaving the office? Answer the call on the mobile app instead.

Integrate your desk phone, mobile phone, PC or Mac, laptop and tablet to easily manage your calls, set-up video conferencing, access call history and more – all via the cloud.  With hunt groups, call queues, auto-attendants, conference rooms, PCI compliant call recording and much more, the days of expensive on-site PBX’s are in the past.

Integrate CallSwitch into MS Teams to have the power of a full featured PBX and free calls with the collaboration of Teams, or use our Direct Routing to replace Microsoft’s Call Plan.

This is business changing. This is what we do.
