Does Call Manager v8.5 support paging on mulitple phones (groups of phones) simultaneously or does it require another product? We purchased IPSESSIONs a while back to use for paging but I was told that the function was in Call Manager. We have had CM for a few years and we are just now getting ready for paging and some other UC functions.
Next question. With IP sesssions I have to configure on IP multicasting throughout our network to support paging. Can I assume that even if Call Manager supported it internally without the necessity of IPSESSIONs that I would still need the IP Multicasting protocol support on our entire network for paging?
Chris is right that 3rd party app is needed. But I don't agree that Informacast is the best one.
What about an alternative in 2Ring PHONE SERVICES which can deliver much more than just paging?

FREE and TRIAL licenses are obviously available.
As for your 2nd question, yes, multicast should be enabled in entire network.
