What codec types are supported by the IP Desk Phone?

The correct answer encompasses a broader and more versatile range of codec types that are supported by an IP Desk Phone. Understanding these codecs is crucial for ensuring high-quality voice communication over IP networks.

The codec g.711 is a standard codec that provides uncompressed audio, enabling high-quality sound transmission with minimal latency. It operates at 64 kbps and is widely used due to its good balance between audio quality and resource requirements.

g.723 and g.726 provide options for compressed audio transmission, which allows for better bandwidth management. g.723 is a low-bitrate codec typically used in low-bandwidth situations while maintaining acceptable sound quality, making it advantageous for VoIP applications. g.726, on the other hand, is another codec that compresses audio to reduce the bandwidth needed for communication while still delivering acceptable audio fidelity.

g.729ab is a variant of g.729, which offers efficient compression suitable for voice traffic. This codec is particularly useful in environments where bandwidth is limited, as it operates at a low bitrate while still providing clear voice quality.

The combination of these codecs allows the IP Desk Phone to adapt to various network conditions and user preferences, making it a versatile tool for voice communication in different scenarios.
