I believe the concept of AEC (echo cancellation) is sufficiently well
understood that it can be implemented without a reference.

Specific echo cancellation algorithms are typically quite fluid and/or
proprietary; I do not believe that the Internet would benefit from
referencing any single AEC algorithm.
Two endpoints do not need to agree on an AEC algorithm to function.
