Opus codec support

WARNING: opus codec is listed here as an experimental feature, without production-grade support at the moment! Due to limited memory, the opus codec is not available for D120.

iLBC codec support

LIMITATION: If incoming SDP has different ptime (eg. ptime=30) than the configured ptime (e.g., Packet Size=20), the behaviour is undefined. To prevent this, please make sure the phone is configured with correct ptime.

Supported Codecs on D305, D315, D335, D345, D375, D385, D712, D715, D725, D745, D765 and D785
