I’ve this system working for several months flawlessly, all of a sudden all incoming calls now go to a busy signal. Outgoing works fine.
I’ve tried restarting and restoring from working backups. Either case, it will answer one call, then all subsequent calls go to a busy signal.
I’ve also tried 2 different sip trunks – skype & flowroute, with only one active at a time, same result.
Any ideas?
Thanks.
