no, not yet. […]
Regarding your 2nd paragraph (MGW telling MSC which transcoding matches it support), I think the idea behind having an MGW is precisely not needing to worry about that, as in the MGW should in theory be capable of transcoding whatever you throw at it.
Whatever limitations our MGW has in transcoding/handling different codecs on each conn side, it means we need to add some hacky code in our client to avoid those imho, nothing more.
