Konftel 300M – the conference phone for the mobile office


The Konftel 300M is perfect for companies that have mobile communications solutions. In addition to benefiting from the flexibility of its mobile solution, your company can have an uncompromising conference phone with smart functions and Konftel’s patented audio technology, OmniSound®, which ensures crystal-clear sound on all conference calls. The battery provides up to 30 hours of talk time and recharges when you place the Konftel 300M in its accompanying charging cradle. (You can use the phone while it is charging.) Other useful features include the ability to record to an SD memory card, SMS capabilities, and a conference guide that helps you save call groups—a huge help if you make regular multi-party calls. The USB computer connection enables you to make VoIP calls, and you can use the Konftel 300M in environments with unified communications solutions.
