I had problems with these kind of streams in the past

If this QCLP tag identifies TIA/EIA/ISS-733 conforming
data then this is just wrong. See, these are sampled at
8kHz -- period. this is no optional recomendation but
a requirement (You can take a look at section 2.4.1
of the all infamous C.S0020-0with3Gcover.pdf if you
feel like it) Now, if this patch works out decoding
for you I'd suggest adding a warning to state out-spec
data, at the very least.

I also seem to recall I had other troubles decoding
this kind of data. I will try to remember.
