You do not give any details of who/where the caller is that is listening to the corrupted MOH audio. Have you tried with a local SIP phone to see if it is a corruption locally or in the onward transit (whatever that may be) - For example, GSM phones will often distort music as the codec is designed for speech. This is largely unavoidable.
