Hi
I'm not having a problem with phantom digits being recognised, When pressing a digit while my custom recording is being played is not being accepted by the system unless there is a silent spot in the custom message. It's as if the custom message being played is drowning out the DTMF tone coming back in but the volumes are the same on the default system and my custom recordings.
As mentioned earlier, I can enter numerical passwords and be accepted 100% of the time when a default system recording is being played.
