Our company is using a homegrown Asterisk VoIP server solution. We use DHCP and TFTP to auto-configure Linksys SPA phones. When we
change the configuration, we would like the phones to reload the config
files. Maybe we could use multicast to force the phones to restart
and/or reload the configuration since we know that Linksys phones
respond to some multicast commands. Where can we get the list of those
multicast commands, possibly with details (packet formats, command codes)?
