How will you power this phone?
Most desk phones run on Power over Ethernet (PoE). If your switch or injector provides PoE, you need nothing else. No PoE? Add the power supply made for this phone.
We don't stock this phone's power supply online yet — if you don't have PoE, check out as-is and we'll confirm power with you before it ships.
Blind shipping available — your address on the label, no Reef-branded paperwork in the box. Choose it in your cart. How it works
Every Reef phone already includes our free 10-year warranty with advance replacement. Reef Support adds the people: expert Cisco engineers on call, a guaranteed response time, and onsite dispatch when a phone goes down.
Response time
Term
Coverage carries a 20-phone minimum — the contract quantity adjusts automatically.
Choose a response time and a term above to add coverage — or select "No support plan."
Coverage activates once we register your serial number(s) — we'll email you a secure form right after checkout. Buying for a tax-exempt organization? Your exemption carries over at checkout.
