We're building out a prepaid calling card system using IVR instances on Voice Gateways with a modified version of the Debit Card script. The Voice Gateways communicate back to billing software via radius, and so far everything has been going great! Last week we met with the customer and were thrown a bit of a curveball. They are requesting that when the called party picks up the line they are presented with a recorded message and an option to accept or deny the call. Something like: "This is a Prepaid Call from <name>. To accept press 1. To deny press 2, or hang up." To add a bit more complexity, they do not want the calling party to be able to speak with the called party until they have accepted the call. I've been looking around at a few different ways to do this but so far I'm drawing a blank. Any help would be greatly appreciated. Thanks!
