Abstract
This disclosure describes a network-aware codec negotiation technique for satellite voice communications. Devices connected to satellite networks face issues such as high latency and low bandwidth that can cause modern High-Definition (HD) voice codecs to fail. This leads to call dropouts and/or unintelligible audio. The techniques described herein utilize client-side logic on the user equipment (UE) that forces the use of the Adaptive Multi-Rate Narrowband (AMR-NB) codec via the session description protocol (SDP) offer that is sent by the UE when a satellite connection is detected. This ensures a stable and reliable call, with priority given to intelligibility and reliability. The use of AMR-NB also guarantees interoperability as AMR-NB is universally supported.
