Summary:                    Zaptel doesn't detect 2100hz EC disable tone
Description: 
In an installation who has a lot of issues with faxing (mostly
communication errors), I noticed that Zaptel isn't detecting the 2100hz
tone and therefore is not disabling EC for that channel.

I expect a line like that in syslog:



Jul 16 14:23:04 pabx kernel: zaptel Disabled echo canceller because of
tone (rx) on channel 1



But I get it only very rarely. Faxes are sent and received via a telco
provided PRI. The board used is a TE110P. There is also a TE410P on the
same box but it is not used for faxing.

echocan: Improve interface for echo cancelers.

Echo cancelers are now able to report if they are able to automatically
disable
their NLP portions in the presence of tones in the audio stream.   Also,
the
interface is changed to allow user space to just disable the NLP portion
of the
echo canceler.  These changes improve fax and modem handling in DAHDI.

Patch by: kpfleming

Also contains improvements to CED tone detection.
