Hi,

Where can I get a copy of the Mitel, Bellcore or other test tapes?
Are there any public-domain DTMF test suites available?

Thanks,
Scott

You can't get the Mitel or Bellcore tapes any more. There are no other 
widely accepted test tapes/disks available. If you have an old unusable 
Bellcore set, I might be able to let you have pristine transciptions 
into wave files. The material is unavailable, but it is still copyright. 
If you don't already have a copy I can't help.

The DTMF decoder in spandsp at www.soft-switch.org comes with a test 
suite that mirrors the tests on the Mitel test tapes (except for the 
talk-off tests, where I use my transcriptions of the Bellcore tapes).

Regards,
Steve

That's an odd situation--desirable materials which are commercially unavailable 
but still copyrighted.  It's as if they want you to obtain them illegally since 
it is impossible to obtain them in a legal manner!

There is a great deal of recorded music, and probably movies too, which 
you can no longer buy on any medium. However, unless the copyright has 
expired it is still illegal to make copies outside the fair use 
provisions some countries have established. One could argue that copying 
these tapes, that are no longer available from the copyright holder, is 
fair use, but that is not a call I intend to make.

Regards,
Steve

Is there anyone out there who's willing to sell me their copy of the
Bellcore tapes?

Thanks,
Scott
