"     I'm looking for source(s) that sell  the FX-118  chip. This  is a
double (ie:full duplex) speech inversion encoder/decoder chip used
mostly in wireless telephones. Any suggestions ?
"
 
I don't know where you can get it, it would help if you'd said who
made it.
 
But are you looking for this because you need that particular IC
(like for replacing something), or just that sort of device?
 
I have an eight year old MX-COM databook, and it lists a number
of IC's for audio scrambling and voice band inversion.  When I
first got the data book those particular IC's did look very tempting
for various non-scrambling applications.
 
The address on the book is:
    MX-COM, INc.
    4800 Bethania Station Road
    Winston-Salem, NC 27105-1201
 
The book doesn't list distributors, so I don't know who locally
would carry their line (assuming they still exist).
