Explanation
In a multisite Cisco UC deployment, intrasite communication refers to calls between endpoints within the same physical site, where bandwidth is typically abundant (LAN speeds). For intrasite calls, high-fidelity, uncompressed or wideband codecs are recommended since bandwidth is not a constraint. (A) G.711 is the standard PCM codec at 64 kbps providing toll-quality audio and is the default intrasite codec. (D) G.722 is a wideband HD voice codec at 64 kbps offering superior audio quality (7 kHz bandwidth vs. G.711's 3.4 kHz), making it ideal for intrasite use. The other options are intersite (WAN) codecs: (E) G.729 compresses audio to 8 kbps and is recommended for bandwidth-constrained WAN links. (B) G.728 is a lower-bitrate codec (16 kbps). (C) H.264 is a video codec, not an audio codec.
