Get rid of cables in your meeting room and improve team collaboration. The Snom C620 wireless conference phone uses DECT 6.0 technology for completely wireless conferencing. The system includes a SIP-DECT base and docking station and can charge your phone for up to 24 hours (12 hours for wideband audio) of talk time. Simply place two wireless microphones in your phone's integrated charging bay and you'll be ready for your next call. The C620 can be placed completely freely in your meeting room without tripping over cables. Less frustration and richer conversations with a wireless microphone. Do you need to accommodate larger gatherings? Easily add up to two C52-SP DECT expansion speakers to accommodate the most active participants. Now you and your team can hear, reach out, and speak clearly without yelling across the table.
