[asterisk-users] analog channels calling out not detect DTMF

[Jerry Geis]

I have a TDM2402E card.

Occasionally I have noticed that a number I call that gives and IVR
the DTMF keys are not detected. All other times the DTMF works fine.

/proc/interrupts is:
           CPU0       CPU1
  0:  500798020  500749281    IO-APIC-edge  timer

What might I look to getting this to work all the time.
