Original DTMF code "111" generated by Audacity , 3 seconds

http://www.filedropper.com/dtmf1113s

The same file played by Asterisk + Celliax
and recorded by Audacity

http://www.filedropper.com/dtmf111s3asterisk

Signal drops has been manually repaired ( select + copy + paste
into no-signal periods)

Please open by Audacity and select
Analyze / Plot Spectrum
from menu

Open 2 above files in 2 instances of Audacity to get a view
of 2 audio spectrums plotted side by side.

It looks Asterisk + Celliax runs underpowered in processing of
audio files played as MusicOnHold.

More tests to come soon.

Please let me know your opinion.
