[asterisk-users] DTMF digits falsely detected

[Vieri]

Hi,

I have a context that basically does:

Wait(1)
Background(message)
WaitExten(10)

_6XXXXXX,1,DoSomething

The problem is that when I reach this context and press some digits (eg. 6566604) then I can see in the log that Asterisk reads 6655666.
So it's actually reading the digits twice.
How can I avoid this?
Incoming channel type is ISDN (mISDN).

Thanks,

Vieri
