Full Duplex Speakerphone Environment Setup
(DP5130-FDSL)
The DP5130-FSDL has a powerful integrated full duplex speakerphone that provides
bi-directional voice transmission, allowing simultaneous talk. The microphone is
located on the front right side of the telephone, so all objects need to be kept well clear
of that area to ensure there are no reflections that might generate an echo or other
feedback. In a full duplex speakerphone environment, a number of conditions
including room acoustics, network conditions, or the other party’s equipment can
induce echo, a short silence, or clipped speech, so it is important to use the following
recommendations for optimal performance.
