Hello @Liz_Chamas ,
Welcome to the Poly Community.
An analog SoundStation, unlike the quoted SoundStation IP, does not have any logic that would prevent you from dialling and/or ability to display any messages.
An analog phone simply sends the digit's in DTMF to the PSTN which then decides what the phone can do.
I suggest you work with your PABX vendor.
