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've patched the code and rebuilt asterisk. I am doing some more testing,
but I don't think the patch solved the issue. Now, it seems that the second
digit is missing. DTMF log below (same sequence is entered--823229999):
