[asterisk-users] fxotune Error - Found a solution in my case

[John French]

I finally isolated the problem, hope it works for you too. The default -m (silencegoodfor) default of 18 seconds is too long for my telco and the test is getting interrupted. I listened in on the line with a splitter and realized what was happening. I had to set -m down to 15 seconds in my case and it works. Also, I'm running zaptel-1.2.12 so I had to svn checkout the current zaptel trunk to get a better version on fxotune as the one in 1.2.12 has very few options. I still have some echo but at least I'm on the right path now.
Also anyone have any tips on plotting the -d values?

This isn't any help, but I've just seen this myself on one of my units.

Hardware wise it's indentical to a dozen other units I've built, and it 
does work OK, I just get the same error as you when trying to fxotune it.
