Summary:                    [patch] Incoming DTMF causes "Cannot handle frames
in 2 format" error, call dies
Description: 
All incoming DTMF tones over my DAHDI interface (a PRI) cause the following
error:

[May 16 08:38:27] WARNING[2387]: chan_dahdi.c:5624 dahdi_write: Cannot
handle frames in 2 format
[May 16 08:38:27] WARNING[2387]: file.c:723 ast_readaudio_callback: Failed
to write frame
    -- Hungup 'DAHDI/1-1'

The call is dropped and this error appears on the Asterisk console as soon
as any DTMF is received over the DAHDI interface. Calls otherwise function
normally until any digit on a phone's keypad is pressed while calling in.
