Snom C520 is an IP conference phone with two wireless microphones. Perfect for small businesses, home offices, and even multi-room conferences, C520 provides full-duplex HD wideband audio quality on group calls. It features a microphone in the base plus two microphones that rest in the base unit, but can be detached for wireless placement, giving you an extended conference range. The microphones communicate with the base using DECT, which gives you excellent audio quality with a 50m (164ft) wireless range.
Snom C520 supports up to 3 SIP accounts with concurrent call management. C520 lets you bring smartphones and headsets in the conference using Bluetooth. If you need more coverage, you can connect up to three C52-SP expansion microphones (not included).
