A while back I posted to this list regarding implementing multi-cast paging in Asterisk.
I have now been able to get some additional information on how this is implemented and so I'll pass it on to the list in case anyone wants to take up the challenge. Personally I'm hoping to do some additional work on this in the near future when time permits. I'd also like to add this to the bug: http://bugs.digium.com/view.php?id=7172 but its closed. Can someone do that for me or open it? ------ This is the format of a multi-cast UDP packet that triggers the phones to listen for a page: The server sends a command to all phones in the page group via multicast. The format of the command is: - First four bytes: command to start listening to a group page message - Second four bytes: multicast IP address to listen on - Ninth byte: group number; 0 for all phones (only zero is support in current firmware) - Tenth byte: reserved, must be 0 - 11th and 12th bytes: multicast port number When the caller hangs up, the server sends another multicast message alerting the listeners that the call has ended. ------- Regards, John Lange _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-dev mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
