Does this just sound worse than it is?

You haven't missed much.
With SBC you are out of luck, since Asterisk doesn't detect dialtone  ( 
it dials blind, sometimes too quickly for the CO to catch the first 
digit, resulting in wrong numbers )) or stutter dialtone either, and 
reportedly has had any indication of the DC status of a POTS line 
removed due to problems.
 
Only choice would to port the number to a VOIP provider and provide the 
VM in Asterisk.
Similar problem with Vonage VM.
