G.711 (μ-law / A-law) and optional G.729A/G.729AB audio codec implementation for
[rvoip](https://github.com/eisenzopf/rvoip). Pulled in transitively by
`rvoip-media-core` to provide the baseline narrow-band codec every
beta-tier SIP profile requires (RFC 3551).
## Status
**Beta candidate** — part of the `rvoip-sip` 0.2.x beta train. The
G.711 implementation is RFC-compliant and table-driven. G.729 support is
available behind the `g729` feature as Annex A speech plus optional Annex B
VAD/DTX/CNG; full-complexity base G.729 is not implemented.
## Install
You usually don't depend on this directly — depend on
[`rvoip-media-core`](https://crates.io/crates/rvoip-media-core) which
re-exports the codec surface. If you need the raw G.711 tables in
isolation:
```toml
[dependencies]
rvoip-codec-core = "0.2.2"
```
