"To accept this call, Press 0": Collect calls from prison inmate
When I press "0" to accept a collect call from an inmate. But today there was NO tone when I pressed the 0 on the keypad. I get abt 15 seconds to accept the call. But I can't. Seems like an obvious easy problem to fix - adjust a setting. But no one knows how to do that. rsvp and HELP.
