What Codecs Provide the Best Sound Quality?

For the best sound quality, all calls in CommPeak Dialer, CommPeak Cloud PBX, or CommPeak Softphone are default switched to G.722 HD wideband audio codec, which provides crystal-clear phone calls and sharper, crisper voices.

❗️

IMPORTANT

Please note that call quality depends on both the device you use and your provider.

If you're using a provider that supports G.722 wideband codec, HD will provide superior call quality.

Also, you can maintain excellent voice quality and lower bandwidth usage with codecs such as G. 711u/a or G.729a, assuming you have the bandwidth available.
