Summary:                    Inband DTMF begin event not fired correctly
Description: 
When a channel is configured to send DTMF as Inband (SIP, DAHDI, ...), a
"DTMF begin" event is missing, leading to several errors in regenerated
DTMF length and/or sometimes duplicate or missing DTMF.
Tested on 1.4.26, 1.4.27 and 1.4.28-rc1

Maybe has some relation to bug: https://issues.asterisk.org/view.php?id=16243,
apparently working in 1.6.1.9 but
never fixed in 1.4 branch..

inband to rfc2833"

The reason that issue wasn't committed to 1.4 was because it was a complete
rewrite of the DSP code, which would not have been appropriate for 1.4.
