This has been discussed, and the conclusion is that there is no specification which forbids using the same code name for two different codec numbers. That is not recommended, however. It is not recommended to use a payload number that has a static assignment (RFC 1890) for any codec other than the static assignment, but it is allowed, as long as an a=rtpmap line describes the assignment. Even if a payload number has a static assignment, it is recommended to provide an a=rtpmap line for it.
