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?

Still not fixed in 1.4.38 ... is anyone actually working on this?
Is there anything we can do to help out?
