I need to devise a way to keep users from playing touch tones over the paging system. If you can suggest a way to prevent users from sounding touch tones over the paging amplifier circuit post it here or E-mail direct. Be advised that my ISP's anti Spam software will generate a service message to which you will have to respond in order for me to receive your e-mail.

[TELECOM Digest Editor's Note: At least on the older Bell switchboards, there was a certain contact on the network (inside the switchboard) to mute your earpiece from the audio on touch tones while still playing them out over the phone. It was generally only done for switchboard operators to prevent them having to listen to the tones all the time as they placed calls. PAT]
