[Freeswitch-users] Anyone have info on multicast paging FS and Linksys SPA phones

Scoured web sites, traces, etc. for a year no luck. Anyone out there with some info? Can't get paging to work on Linksys SPA962s, I have check the multicast address and it matches FS. Here is what happens: If I connect my old Linksys SPA9000 PBX and power it on, then turn it off, FreeSwitch paging works on all the phone! If a phone is powered off, FreeSwitch paging no longer works on that phone. Power on/off SPA9000 and all is well. Anyone out there have it working that could tell me the secret? I am using *11 to page to trigger the rtp_multicast_page extension. Thanks in advance! MarioG
