Mitel 56005586 SX-200 / SX-2000 / 3300 ICP telephone system SIP Handset

The Mitel 56005586 is a Mitel 5220 IP Phone, a dual-port Gigabit desk telephone from Mitel’s 5200-series SIP handset range built for the 3300 ICP and later MiVoice Business platforms. It gives a user standard call handling plus a small set of programmable keys, and was one of the more widely deployed phones on the 5200 range thanks to its lower cost relative to the display-rich 5300 series.

Mitel’s IP phone ranges (5200, 5300, 5300 IP, 6900) were sold alongside the 3300 ICP and later MiVoice Business controllers across small, medium and enterprise sites, and firmware/provisioning is generally shared across a whole controller software release rather than being phone-specific. As with any used IP handset, confirm the firmware and provisioning method your system expects before deploying it.

Mitel PBX systems from this generation remain in active service across many established telephony deployments, and genuine spares such as this one are a routine requirement for maintaining full system capacity, restoring redundancy after a component failure, or expanding an existing installation. Tech-Star (UK-based, shipped worldwide) stocks Mitel components to support ongoing PBX maintenance projects. Please contact our sales team for current stock and pricing.
