Purpose-built desk phone

The Avaya CCX 400 is a wired VoIP handset designed for professionals who handle high call volumes. It supports up to 24 simultaneous SIP registrations so receptionists and team leads can manage multiple queues without switching devices. A dedicated Microsoft Teams button provides one-tap meeting entry for organisations standardised on that platform. The 5-inch colour LCD touchscreen replaces traditional navigation keys with a familiar smartphone-style interface.

Thermals noise and power

The unit draws power exclusively through its two Gigabit Ethernet ports using Power over Ethernet, eliminating the need for a separate mains adaptor. With no internal fan or spinning drive, the phone runs completely silent during idle and active calls. The dual-port design allows the handset to sit inline between the wall jack and a workstation, passing network connectivity through without an extra switch port. Heat output is negligible in normal office ambient temperatures.

Accessories and software impact

A single USB-A 2.0 port on the side accepts a wired headset or a USB storage device for local contact backup. The Microsoft Teams integration is baked into the firmware, so the dedicated button works immediately after provisioning without extra licences or client-side installs. No bundled headset, stand or wall-mount kit is mentioned in the supplied data, so buyers should verify mounting requirements separately.

Questions about this item

How do I connect the CCX 400 to the network and power it, and which port mistake should I avoid?

Plug the network cable into one of the two Gigabit Ethernet PoE ports so the phone receives both data and power; using the USB-A 2.0 port instead will not supply PoE and the phone will not start.

What part of the CCX 400 is most likely to need replacement after extended daily use?

The 5" color LCD touchscreen and the mechanical hookswitch are the components that typically wear first with heavy tapping and frequent handset lifting.

What is the first limit I will hit when keeping all lines active on the CCX 400?

The phone supports 24 SIP registrations, so the 24-line registration ceiling is reached before any other resource constraint.
