Yes.  Jean-Marc has made the API more similar. 

Jean-Marc:  Have you looked at the API we have for the 
asterisk/iaxclient jitterbuffer?  It's pretty close to what you have now 
-- the major difference is that your jb still assumes it can "own" the 
data passed in -- it copies it, and it destroys it at will.  With the 
API I put together, the jitterbuffer only keeps a poiunter to the data, 
and considers it opaque -- if it wants to destroy the data, it needs to 
return the pointer with a flag, and then the caller is responsible for 
whatever cleanup is needed.

Here's that API:

It would be cool if the speex JB could use a compatible API, then people 
could always mix/match these things, and see which one works best for 
different situations.
