Compatibility & Buying Information
Exact SKU: This page is for Mitel part number 50009433, the 6910 SIP / 3PCC phone intended for compatible Open SIP and third-party call-control environments.
3PCC / Open SIP Version: This SKU should be selected when a standards-based SIP endpoint is required for a compatible hosted, cloud, UCaaS, or on-premises SIP communications platform. Available calling features depend on the connected provider and provisioning configuration.
Eight Programmable Keys: The 6910 provides eight physical programmable personal keys with LED indicators, giving users direct access to commonly used line appearances, speed dials, busy-lamp fields, and other provider-supported features.
Up to 24 Lines: Mitel's SIP documentation states that the 6910 can support up to 24 call lines. Actual configured line capacity and behavior depend on the connected SIP system or service provider.
Gigabit Ethernet: The 6910 provides two fully switched 10/100/1000 Mbps Ethernet interfaces. A computer or compatible network device can share the wired network connection through the phone's PC pass-through port.
No PoE Output from PC Port: The secondary Ethernet port passes network data but does not provide inline PoE power to the connected computer or network device.
PoE or Local Power: The phone can be powered through a compatible PoE network connection. If inline power is unavailable, a compatible Mitel AC power adapter can be used and is sold separately.
Wired Headsets: The 6910 supports standard 4-pin analog headsets as well as compatible DHSG / EHS headsets through its convertible headset interface.
No Built-In Wi-Fi or Bluetooth: Unlike the higher-end 6920W, 6930W, and 6940W models, the 6910 does not include integrated Wi-Fi or Bluetooth. Wireless requirements should be planned separately.
No USB Host Port: The 6910 is designed around wired handset, speakerphone, and analog / DHSG-EHS headset use rather than USB headset and accessory connectivity.
Desk Installation: The included reversible stand provides 30-degree and 60-degree viewing positions for desktop use.
Wall Mounting: Wall installation is supported using the optional Mitel 6900 Series Wall Mount Kit, including part number 50008299.
SIP Documentation: Part 50009433 should use Mitel's 6910 SIP User Guide, Installation Guide, and Quick Reference Guide rather than the separate MiNet documentation branch.
Best Fit: Mitel 6910 50009433 is well suited to offices, customer-service teams, shared workspaces, contact-center users, and managed Open SIP deployments that need more programmable keys and line capacity than an entry-level phone while retaining straightforward physical controls, Gigabit networking, and HD business audio.
