Jim, two makes come to mind:
Wavecom and Falcom.  I would be VERY interested in hearing comments from
others on the list who have used these or other modules in projects.  I'm
currently in a stage of a project where I have to start thinking about which
module to choose - I haven't used one yet.  My interest lies in the data
side of things, but I may use DTFM tones, which would of course be voice.

Ironically these modules cost much the same as midrange cell phones (but no
one will trash your product to steal it <g>).

Cheers
 Roland
