Professional Conferencing Speakerphone in Pakistan – AVer VC520 Pro Expansion Speakerphone:

The Aver VC520 Pro Expansion Speakerphone is a professional conferencing phone designed to expand the pickup range and maximize audio coverage. This full-duplex speakerphone is equipped with a powerful speaker and a mic that picks up voice within 360° at up to 15′, giving you configuration flexibility regardless of your room design or seating arrangements in meeting rooms and classrooms. To avoid crowding around one speakerphone, you can daisy-chain this Expansion Speakerphone to the speakerphone that’s included with the VC520 PRO video conferencing system and achieve a 30′ voice-pickup radius.
