The Linksys SPA line of phones (941, 841, 942 etc) all support paging using a RTP multicast address "224.168.168.168:6061".
Beyond that I don't have much technical detail on how this works. I assume that if you send RTP packets out to that multicast address the phones will see them and send them to the speaker of the phone. As far as I'm aware this is not currently supported in Asterisk. Does anyone have any suggestions as to how to generate RTP packets to test if we can get the phone to work with paging? -- John Lange OpenIT ltd. www.Open-IT.ca (204) 885 0872 VoIP, Web services, Linux Consulting, Server Co-Location
