To nail this down, you might want to start by just using one codec 
throughout the system -- e.g. just use a-law, then test everything -- 
SIP phone to SIP phone, SIP phone to voicemail etc. That way you know 
since everything's talking to each other using one codec, there's 
probably something else wrong in some other config file.
