What is a refurbished device?
A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.
Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

Cisco CP-8811 1-Line SIP VoIP IP Phone HD Voice PoE Business Wideba...
We ensure secure processing of your payment information and do not retain or have access to your credit card details.
The Cisco CP-8811 is a professional-grade SIP VoIP desk phone built for business environments. Featuring HD wideband audio, a built-in full-duplex speakerphone, and 802.3af PoE support, it delivers clear voice communication without requiring a separate power adapter at the desk. Compatible with Cisco Unified Communications Manager (CUCM) and standard SIP-based phone systems. Backed by a 12-month Reboot IT warranty and free standard AU shipping.
The CP-8811 is well-suited to business environments where a single dedicated line and clear voice quality are the priorities — reception desks, private offices, help desk positions, and shared workspaces. The monochrome LCD clearly shows caller ID, time, date, and call status, and the physical keypad with dedicated function keys keeps call management intuitive without a learning curve.
HD wideband audio is the standout improvement over older analogue or legacy IP phones. The G.722 codec captures a broader voice frequency range, making remote conversations sound noticeably closer to in-person speech. The full-duplex speakerphone performs well in private offices, handling both sides of a conversation simultaneously without the echo typical of half-duplex units.
For IT teams deploying into Cisco UC environments, the CP-8811 provisions through standard Cisco Unified Communications Manager workflows with DHCP and TFTP auto-configuration, minimising hands-on setup time per device.

Fantastic service
I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!
Great service. Product in great condition and exactly what i want. I wanted this for a specific purpose but i dont need to spend $900 on a new one.
Excellent work
exactly as described and works well , just like the staff down there. 10/10
Very happy, thank you
Just having trouble greeting it linked to the internet otherwise it’s okay.
Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.
The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
