asterisk users - Mar 2005 - Telecom echo cancel disable

Disabled echo canceller because of tone (tx) on channel 10

I understand that the PSTN companies use their own echo canceller's,
send a tone across 2100hz, the problem we're having is people are
complaining of echo on random calls. I'm assuming this may be the cause.
Is their anyway to 'ignore' the disabling of EC? Or would be just be a
manual code change..

Yeah.  Edit zconfig.h and there's an option to ignore 2100hz.  I didn't
know what caused the 2100 until you said something.

Too hard to say. My problem is with a Channel bank, if it made it any
better then it's very little.

	I also have users that suffer from random echo on a British
Telecom provided PRI.
	 
	Can you confirm that this has improved your user experience ?
