Derrick, I called her, she pushed buttons, I heard them. I called their location from my Cell, pushed buttons, no tones. Just heard a slight click on my cell. I called my cell from their location, (and called one of my other customers auto-attendant) I could hear their tones, and the auto-atten responded to my tones.
The lines are plain old POTS lines.
It is apparent that on an inbound call, I can't generate DTMF to the calling end. On the old Executech's, sometimes you had to put the caller on hold, then go back to make the DTMF signaling work (I think, been years since I had that) but I put the phone on hold, heard their music on my cell, went back on and tried to DTMF, same as before.
Leave it to me to get this goofy crap.
