We have a client with 150 phones across 5 physical locations. They want a “page all” button, that when pressed, puts every phone, in each of the 5 locations, off-hook and plays the page audio. We do this with multicast when it is a single location on a single subnet. But, this is across 5 physical locations, each location behind a separate internet connected firewall/router.
It looks like the Algo 8301 will accept a SIP call and then transmit a multicast page. The thought is that we could put an Algo at each location, put each Algo’s SIP extension as a Page Group member, then when somebody dials the Page Group number, each Algo receives a call and in turn creates a multicast stream that each phone plays.
Is this the best way to achieve 150 phone paging, across 5 locations, with only 5 RTP streams and not 150 streams? Is Algo the most reasonable cost device to do this ($350 each Algo 8301)?
Thanks in advance
