I'm replacing an old Partner system with an IPO. One of my buildings currently has the Partner system with the AT&T PagePac 6 Plus. Page port from Partner connects to PagePac and it has 3 zones. Currently works perfectly fine. I do not have an IP500 at this site, only IP phones (9608G). I've used a SNOM PA-1 successfully in the past where it connects directly to a Bogen amp (no zones). I'm guessing the Snom output is a line level output so it's not working when I connect to the PagePac. I still need to have the ability to use the zones/PagePac. Anyone ever set this up before like this? Do I need another device between the Snom and PagePac? Or can recommend a working and relatively inexpensive solution. Thanks in advance for your assistance.
