Audio Codec
The door phone supports three types of codec(PCMU, PCMA, and G722) for encoding and decoding the audio data during the call session. Each codec varies in terms of sound quality. You can select the specific codec with different bandwidths and sample rates flexibly according to the actual network environment.
Set it up on the Account > Advanced > Audio Codecs interface.
Please refer to the bandwidth consumption and sample rate for the three codec types below:
Video Codec
