these bugs are in asterisk, and sometimes they relate to the products
that asterisk uses.
-* The MP3 decoder is completely broken
-
* The translator API may introduce warble in the case of going in both
directions, but I haven't verified that. The trouble should only enter
in the case of mismatched frame lengths.
+
+* In general Asterisk is a very new program, and there are liable to be
+ many bugs yet to be discovered, so if you think you've found one, please
+ be sure to report it.
