[asterisk-users] DISA and DTMF detection problem w/ FXO port on a TDM400

Hi!

I'm trying to configure a DISA setup (Asterisk 1.4.11). Only, executing
DISA seems to prevent any DTMF detection capability when using the FXO
port of the TDM400.

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 not
other problem detecting DTMF that we are aware of...

I see no active bug related to DISA at bugs.digium.com...

Any idea?

Ben.

*Code:*

---------------------------
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 ...

; --- Config A --- ;

*Code:*

exten => 111,1,Answer
exten => 111,n,Authenticate(111)
exten => 111,n,DISA(no-password|internal)

; --- Dial sequence --- ;

*Code:*

PSTN line -> TDM400
enter extension 111 -> dial tone
enter password 111 -> "new" dial tone
enter extension -> I still getting the dial tone whatever I'm entering
timeout.

Here the debug log:
