I'm not sure if this is much use to your setup - but I've implemented a public announcement system (in UK sometimes called tannoy) using a pc and a pair of loud speakers. I used linphonec command line sip client - with auto-answer set. This has the disadvantage, of course, that it can't be used as a phone as well, to make phone calls from the machine driving the speakers (unless you install another sip client) - just as a speaker. You might be able to run linphonec on an embedded platform as well - with a speaker attached. I know there were some compiled for the NSLU2/arm platform already. You will have to combine it with Page() to get multiple nodes working at the same time. I only used one. I did a write-up here - see if you find any useful information: http://forum.voxilla.com/asterisk-support-forum/asterisk-public-announcement-system-loud-ringer-bell-49339.html Sebastian > > I need the system to be resilient to any network partition, so that > anyone can send announces from any mic to all the reachable clients.
