I’m replacing my Meridian Option 11 with an Asterisk PBX. I’ve got parking calls covered, moh covered, even the few pots line requirements covered. My problem is that I need to be able to hook into the existing external paging system. On the Meridian, I simply connect to the paging module though a line card (go off hook, open the circuit, and the audio path is open). I’m wondering if I can use my PC’s internal sound device to accomplish this and if asterisk can communicate through it when asked to do so. Has anyone faced this problem or seen a solution in your travels. Thanks in advance.
