asterisk users - Jul 2008 - User unable to use DTMFs?

Hello

A user seems unable to type DTMF in our Asterisk IVR menu. Can this be
due to their phone or PBX that disables DTMFs when a user is off-hook?

Thank you.

Care to explain the scenario Vincent?
Is it a SIP peer?
what is the DTMF mode set? etc.
