Im currently running an asterisk server (18.104.22.168) we use Linksys SPA942 & SPA962 handsets which are registered as SIP
last week (on Thursday) we had a power cut, since then phones seem to be struggling to register - its like the internet is dropping which causes Asterisk to hang
the server will display a load of "unreachable messages" one minute then i will get a load of messages like
peer 888 is now reachable (10ms / 2000ms)
i understand that Asterisk requires working DNS - i have tested this from the asterisk server which seems to be working (i can ping local/ domain machines aswell as external stuff)
anyone any ideas?
