Double DTMF digits

[DryAquaman]

I have a Soundstation 2201-03308-001.   

The issue is, when I call our conferencing service and press a digit the service hears it as two digits.  For example if I press '3' the service hears '33'.   Is there a setting that can help this?

Found the problem.  Had the user call me and then press a digit.

What I heard was the digit and then an echo of the digit from the surrounding room.

Putting the phone on mute while dialing resolved the issue.

I would say that is more of a work-around than actual fix.  The phone's echo cancellation should actually prevent that from happening.  Are you using external speakers or anything like that?
