Type A IP Addresses:
Asterisk take only one from that list and try to connect, if not succesfull i got ‘unreachable’ i need it to try all ip’s, if i enter good ip manually, it work for some time, till my provider swith the working server farm, and i got ‘unreachable’ again. Any cheapest fxs boxes switch automaticly, asterisk isn’t. Any way ho help me out?
