C620 SIP Wireless Conference Phone

Free yourself from conference room wires, and help your team collaborate better. The Snom C620 wireless conference phone uses DECT 6.0 technology for a completely wireless conference experience. The system includes a SIP DECT base and docking station to charge the phone with up to 24 hours of talk time (or 12 hours for wideband audio). And just place the two wireless mics in the phone's built-in charging bays to get them ready for the next call. The C620 allows total freedom for placement in your conference room–without tripping over wires. With wireless mics, you'll experience less frustration and more successful conversations. Need to accommodate a larger meeting? Easily add up to two accessory C52-SP DECT expansion speakerphones to handle more active participants. Now, you and your team can clearly hear, spread out and speak without shouting over the table.
