Summary:                    DTMF buffer not purged if the dialing timeout
Description: 
When you are dialing, if you got a timeout before complete the correct
number, asterisk Hangup ("not enough digits (and no ambiguous match)...")
but don't clear the dtmf buffer so in the next call you already have the
previous digits...

For example:
 - Dial 12345
 - Wait time out
 - Asterisk Hangup the call
 - You hangup the phone...
 - Start dialing 678 and asterisk think that you dial to 12345678

I test the dtmf_buf-purge-after-timeout.patch in 1.4 branch and in 1.4.14
and it work, but it have no very intensive testing
