Summary:                    [patch] busydetect incorrectly hangs up incoming
call due to incoming DTMF seen as busy pattern.
Description: 
We're using WCTDM FXO modules for an IVR application/voicemail to a legacy
PABX.

Users, and the legacy PABX sends DTMF digits, after dialing voice mail.

Users have these programmed into their phones, dial main number then
pause, then dial known extension. The legacy PABX sends DTMF sequences
immediately the call is answered, to advise VoiceMail that the call is from
inside/out, a forwarded call due to non-answer etc.

Asterisk see's these repeated tone on/off patterns as busy signal and
hangs up.
Having busydetect on is required, as with signalling=fxs_ls requires it.
