As far I know it is impossible to add an encryption provider in the
stack that processes the voice data before it actually goes out on the
line the only solution to do it is to establish a CSD connection, use
Voice Codec (eg. G.726 or G.729) and send data over a CSD connection.
Could you confirm it?
I wrote a VoIP/SIP application and it is easy.. but for this solution I
would like to use CSD connection and I con not find any resources saying
about how to establish a connection, answer and sand a data.

And you want data or voice communications? I'd say that you don't want
to establish a CSD connection for most cases. It would seem that what
they're doing is adding an encryption provider in the stack that
processes the voice data before it actually goes out on the line.
That's quite different than how you'd go about doing this stuff if you
want to send/receive data, instead. If you're going to send data, I'd
just use a socket connection, somehow figuring out the address of the
other end of the connection, and then encrypt the data and send it over
the socket...

Operating System - Windows Mobile 6
Hardware - Not specified because I need write a program similar to
that -
http://www.spyphone.biz/index.php?-352583337 and I can browse a
telephone for this software - I thought about HTC Touch Diamond for
example.
Compactframework - not specified see above.
So finally I need a software that establish CSD connection between 2
windows mobile telephones.

Hmmm. What else might we need to know in order to answer your
question? Windows CE operating system version? Device type/operating
system components included by the device OEM? Server type and
capabilities that you are trying to connect to? What programming
language you're using and what version of the Compact Framework
(since you posted to a Compact Framework group)?
Please read this page, too, while you're at it:
