Hello,
I have a problem of DTMF duplication.
I receive call from my provider with SIP protocol. These calls pass
through an interactive voice menu, using the application Waitexten to
enter a client code. The menu works fine, but sometimes I have DTMF
duplication that prevent proper code entry. All DTMF come twice.

------------------------
As you can see the DTMF come twice, the first with duration of 0ms et the
second with duration of 100ms.
I tried to set relaxdtmf=yes or rfc2833compensate=yes but I still have the
same problem...
Anybody know how I can solve this problem of DTMF duplication ?
Thank you in advance.
Lo?c
