ISDN / CAPI tool vendors

I first tried to find some application that would record my
ISDN-connected phone calls through the ISDN-adapter. No luck this far,
if I do not intend to buy a total new digital telephone switch that
would do it with some add-ons. Seems that there is no much offering to a
single phone line recording task.

Then I thought that maybe I could write one myself if I find some good
ISDN component. Currently I have checked these two tools
http://www.isdn-objects.de and http://www.atelierweb.com

The Isdn-Objects VCL looks quite good, and most of the demo applications
work all right. But the demo to record phone conversations does not work
at all, I don't get anything recorded. Also I'm not sure if this company
is in business any more. The latest updates on those pages or for the
product are over 12 months old, and they also do not answer e-mails.

The Atelierweb's CapiPro has two versions. The free old ActiveX control
seems to hang every time I test it, with their old readily compiled
demoapp. After freezing the application also refuses to close.

The CapiPro VCL version does not hang, and I have been able to get _one_
phone call recorded, but after that never again. Even I think that I
have tested all the possible setting combinations there are.

There's no technical discussion area, so I would need to mail this kind
of beginner question to their Technical staff:( My colleague subscribed
to their Mailing List some days ago, but this far no response has come,
nor link to get to old Mail archives or anything. In general I do not
like this kind of covert, and that way often slow product support style.
The price $89 is not very high, if I just knew it works and records all
right.

So, any comments? Has anyone been successful with any of these two
tools, and is able to record the calls to WAV files? Or does anyone know
some other ISDN tools that would do this?

I have no ambition that I specifically would want to write this
ISDN-recording app myself, I just did not find any ready-made tools and
this is where I am now:) I would still be quite happy even with some
compiled package too.

Thanks for any responses
