[cisco-voip] What would cause DTMF not to go through

[Scott Voll]

Ryan--

Is this an internal only Bug?

I'm getting:

CSCsv04751 Bug Details   The bug ID CSCsv04751 does not exist. Please verify
the bug ID and try again. If you feel you reached this message in error,
please send us feedback including the bug ID in question. (Click the
feedback link in the upper right corner of this page).

So do we know when a new Firmware will be out?  Or a work around for now?
Can they use speaker phone and it work?

Thanks

Scott
