Hi Steve, many thanks for your reply. Would you mind running the following
file through the same decoder?
In this one the audio is not so clean, but I would have thought a good
decoder should still be able to extract the DTMF.
The string sent was again *82779736*91856360** but this time Asterisk
only detected *87936*918636*
I'll have a look at the decoder in spandsp and try to compare it with
the one in Asterisk.
BTW, I'm using Asterisk 1.2.
