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.

I too have noticed the lack of detection of the 2100hz tone with some
testing that I've been doing.  Since I knew which lines had the fax
extensions, I was disabling echo cancellation on those lines, but I do
remember seeing the line that the fax tone was detected in the past.
