Summary:                    DTMF issues in 1.4.19 with missing digits
Description: 
Trying to figure out an issue with DTMF recognition with 1.4.19. This  
is somewhat similar to the issue described here:  
http://bugs.digium.com/view.php?id=11740, but it might be a different  
issue altogether.

I have 1.4.19 running with TE212P on a US PRI hooked up to Time Warner
Telecom. DTMF debugging enabled.

LibPRI 1.4.3
Zaptel 1.4.9

I think it's strictly a flaw in the emulation code. The buffered digits
don't get infused back into the DTMF flow at the right time, and some of
them get "munged up" and never show up. It seems to be a timing issue as
well as well as whether the channel is playing audio at the time DTMF
digits are being entered, IMO.
