Say: If SAY_DTMF_INTERRUPT is set to an ast_true value, jump on DTMF

Browse Source 
Similar to how background works, if a say application is called with
this variable set to 'true', 'yes', 'on', etc. then using DTMF while
the say action is in progress will result in the channel jumping to
that extension in the dialplan.

Say
--------------------------
* If a channel variable SAY_DTMF_INTERRUPT is present on a channel and set
to 'true' (case insensitive), then any Say application (SayNumber,
SayDigits, SayAlpha, SayAlphaCase, SayUnixTime, and SayCounted) will
anticipate DTMF. If DTMF is received, these applications will behave like
the background application and jump to the received extension once a match
is established or after a short period of inactivity.
