Summary:                    Fast RFC2833 dialing results in asterisk generating
overlapping
Description: 
Scenario: call established between 2 rfc2833 endpoints but no packet 2
packet bridge.

If the calling party sends digits really fast (less than the min gap of 45
milliseconds).  Asterisk will attempt to slow down the dialing through dtmf
emulation.  

When this occurs, it is possible that the next digit arrives while the
previous digit is still being emulated by asterisk.  Currently asterisk
doesn't check to see if a dtmf is currently being emulating before
forwarding the start frame of the next dtmf.

This patch adds a check so that if the previous digit is still being
played the start frame will not be forwarded (the end frame will be
enqueued for emulation).

Not only 11740 "briefly mentioned" this behavior but it also has the patch
attached - v1-11740.patch. People also say there that patch fixed other
issues for them so I'm a bit unclear why you isolated it under separaet
issue losing the history etc...
