The Snom C520 is a desktop conference phone for indoor meeting rooms. It combines one built-in microphone with two detachable DECT wireless microphones that reach up to 50 m indoors. Bluetooth pairs headsets and PC conferencing audio, and up to three C52-SP extension speakers can be added for larger rooms. It suits boardrooms and team meeting rooms in Doha, Lusail and Education City.
Three microphones for real meeting rooms
The Snom C520 is a desktop conference phone designed for indoor use. It pairs a microphone built into the unit with a full-duplex speakerphone and two detachable DECT wireless microphones. The wireless units can sit on different desks or be handed to whoever is speaking, so people at the far end of a long table are picked up without leaning toward a single central device.
Dynamic noise reduction and adaptive feedback control work on the microphone signal. The manufacturer also states that the microphones adjust in real time to their positions in the room, so participants can move around without raising their voices. This is useful in rooms where people stand to present or walk to a whiteboard.
Wireless microphones, batteries and range
Each wireless microphone runs on a rechargeable lithium-ion battery rated at 2.4 V and 400 mAh. The manufacturer quotes up to 8 hours of charging, up to 70 hours of standby and up to 8 hours of talk time. The DECT link reaches up to 50 metres indoors, which covers a large boardroom or training room without cables stretched across the floor. The package includes two batteries, so a spare set can be kept on charge.
Connectivity: Ethernet, Bluetooth and SIP calling
The phone connects to the network through a 10/100 Mbit/s Ethernet port. It can be powered over Ethernet (IEEE 802.3af, class 3) or by its 12 V DC power adapter. Bluetooth supports headset pairing with the Hands-Free and Headset profiles, and pairing with a PC or mobile phone lets the room join a conference running on the computer. The unit provides three SIP identities, supports the G.711, G.722, G.726 and G.729 codecs, and supports SIPS and SRTP for encrypted calls. The manufacturer states that it is interoperable with all major IP-PBX platforms.
For halls and very large rooms, up to three Snom C52-SP extension speakers can be linked wirelessly to extend coverage.
Where it fits in Qatar
- A boardroom in West Bay or Msheireb: two wireless units let in-room and remote participants be heard clearly without cables running across the table.
- A seminar room in Education City: Bluetooth connects a PC-based conference, so the room audio runs through the phone.
- A government ministry meeting room in Doha: encrypted SIP calls and password-protected configuration files suit teams with strict security rules.
What to plan before ordering
- The Snom C520 is listed for indoor desktop placement only. Operating ambient temperature is -5 °C to +45 °C, so keep it in an air-conditioned room away from windows and entrances.
- Dimensions are approximately 269 × 282 × 59 mm and weight is approximately 1.5 kg, which suits a conference table with space for the wireless microphones.
- Confirm whether the room has a PoE switch port or a nearby socket for the 100 to 240 V AC adapter.
- For multi-room rollouts, SmartRooms Qatar offers a free site survey so microphone placement and extension speaker positions are planned before installation.
