I need to be able to connect an old PA system to an asterisk box, which basically works as a couple of amplifiers taking an analogue phone signal and playing whatever it produces out of some speakers. There is no on-hook state in the whole setup. Obviously If I just connect the input to a port on an ATA, I'll just get a dialtone played through the speakers. Can anyone think of a way I can attach it, so that people can call an extension that will play through the speakers? The nearest thing I can think of, is getting the * box to call it as an extension plugged into an ATA, then while it's calling plug the line in and transfer it to a non-announcing conference (or similar). This is an undesirable approach for many reasons. (mostly the requirement to set it all up again in the event of a server reset). I have a small pile of ATAs I can play with (well, there's already an atcom 468 in there with a spare port, there's a spare PAP2, a spare Cisco 186 or I could borrow an SPA3k from my home setup) If they'd be of any help. I originally thought about using the sound card, till I saw what was already in place. (The client doesn't like spending money).
