Description:I think echotraining=yes is for the FXS cards but if you happen to have it in your zapata.conf and use it with an X100P dtmf will be very unreliable.  You have to dial very slowly and even then it might not pass dtmf correctly... this is SIP => ZAP.

is no dial tone on any fxs extension

are you saying transmitted dtmf is unreliable or received?

transmitted not totally sure about received.  This was SIP->ZAP

Enabling echotraining increases the pause between the double dtmf tones I'm having a tremendous amount of problems with. This is with the TE410P.

this problem seems to have gone away .... I just tried it.. and its working fine now.  ZERO echo instantly on X100P

ok I was wrong.. I just called my bank and tried the phone banking.. it couldn't understand or get any of the digits I input.

I can confirm the issue also on my t100p/adtran 750 with echo training=yes.
I have no problems acessing internel * menu with dtmf, but
I get random transmited dtmf misinterpretation on 3rd party pbx systems.
When I call one of these systems it will mis-transmit dtmf 1 in 3 attempts turning off echo training it is 3/3

Fixed in CVS.
