We are looking at an Algo 8301 to use for paging (https://www.algosolutions.com/products/audible-and-...), which according to what Algo says (https://www.algosolutions.com/nec) should work as long as the SV8300 and our DT730 IP phones can handle RTP Multicast. Is anyone aware if that is possible or what needs to be done to make it work? The only other stipulation was that the SV8300 support 3rd party SIP device registration.
