Summary:                    [regression] DTMF on agent channel causes high CPU
Description: 
We've recently updated Asterisk to the latest 1.4 version. 
Since then, pressing a DTMF key on an agent channel causes CPU load on a
specific thread to rise with about 10%. Every time a DMTF key is pressed
the CPU load goes up - and it never goes back down again until the agent
logs out.

This results in our entire server going to 0% idle within 20 key presses.

Is there a way to disable DMTF while this bug is being solved so we can at
least make it through?
