[cisco-voip] DTMF issues with VG224 but not other phones (UPDATE)

[Peter Slow]

Lelio,
   that bug is specific to the 5510 DSPs according to the information
in it, your VG224 is equipped with the original PVDMs, which are
c549s, unless there's an HDV2 in it, which im not sure is possible. a
show diag will tell you. Also, theres a very specific symptom with
that bug; at the far end the digits are detected twice. if you are
entering your account number, and press 123, the IVR will tell you it
detected 112233. Is that symptom or somethign similar being reported??
   Is there any sip involved in your environment? tell us more about
the call flow and what devices that call is traversing. from what
you've said, it sounds liek the end users are plugged into the 224.
I'd like to understand how the call is leaving your voice network.
(SIP Trunk, MGCP gateway, etc)

-Peter
