Telephony

Telephony isn’t one decision – it’s five

Whether you’re keeping a legacy system alive, planning your PSTN switch-off, or building a cloud platform that ties into the rest of your business the right answer depends on where you are today, not a generic upgrade path.

Every business’s phone system sits somewhere on a spectrum: Server-based platforms like the Ericsson MD110, through to fully cloud-hosted systems that fold voice into the same platform as your CRM and collaboration tools. There’s no “correct” position on the spectrum. A well-maintained legacy system with no immediate driver to change is a valid choice. So is a multi-site cloud platform built for integration and scale. What matters is knowing which one fits your operation and having a clear, practical path if that changes.

Litenet works across the full spectrum: maintaining and sourcing parts for legacy platforms, defining migration paths off them, managing the PSTN shutdown timeline, provisioning SIP trunking and deploying unified comms that connect your phone system to the tools you already use.
