Description:DISA prevents DTMF detection capability when using the FXO
port of the TDM400.

I got a confirmation from an other user:
http://lists.digium.com/pipermail/asterisk-users/2007-September/196518.html

Also tested with svn 1.4 branch rev82444.

****** ADDITIONAL INFORMATION ******

Below, config A and B and their debug logs.

In Config A I use Authenticate() instead of using DISA password since it
demonstrates that it's DISA that seems to prevent DTMF detection when
using Zap/1. Otherwise DISA works flawlessly when calls are coming from
FXS port (TDM400), IAX, SIP channels.... and we have absolutely no
other problem detecting DTMF that we are aware of...

---------------------------  
zapata.conf
---------------------------
context=inbound-pstn
signalling=fxs_ks
rxgain=10
txgain=3
language=fr
channel => 1

I have tried to change gains without any result ...

Please rerun this test using the latest 1.4 with debug enabled in logger.conf and debug level set to 9, as well as DTMF logging. Thanks.

Sorry for the delay. I can reproduce with 1.4.15. I will try to debug the system during Christmas holidays.
By: Tilghman Lesher (tilghman) 2007-12-24 21:35:13.000-0600

devnullzero:  Excellent.  I look forward to seeing your debug any day now.
By: Benjamin M. (devnullzero) 2007-12-24 22:56:11.000-0600

Here your Christmas gift ;-)

Don't hesitate to ask for anything else.

Example with no detection at all (sometime I can get it working, but it seems to be by pure chance). Via IAX or locally absolutely not problem with DISA.

devnullzero, I cannot reproduce this problem with version 1.4.20 of asterisk.

Can you tell us if you're still getting the issue?
By: Benjamin M. (devnullzero) 2008-05-13 10:05:23

I will try during the weekend. I should have the answer before Monday.
By: Joshua C. Colp (jcolp) 2008-06-10 11:40:41

devnullzero: Any update?
By: Benjamin M. (devnullzero) 2008-06-10 12:37:03

I've tested without great success but the "unexpected behavior" seems to have changed since my previous debug. Saddly, I hadn't enough time to make all the debug. I should be able to check all that in one or two weeks.

Feel free to reopen if you have further information to describe what problem you are seeing.
