Have googled this, but the info is hard, extensive, too complex! Can you suggest something simple?
I use a VPS as a sip (voip) server. Two sip devices use the sip server and both devices are in different locations. If the server goes down = no calls. If the sip server goes down, then I'll only find out when I pick up the phone, or if someone calls me (on my mobile) and says your voip line is not working! I can get nodeping or uptime robot to monitor the VPS but if I don't check my emails every 10 minutes, it's a bit useless. I know I could get messages sent to me a SMS but that too is useless if I am away from home and don't have access to a computer to re-route the sip devices to a backup server. Plus I would then have to manually change the settings in the sip devices.
I thought the internet would have solved this problem but there doesn't appear to be an easy solution. Basically I want 2 (LEB) servers running, and if server1 deadpools/burns/crashes, I want my sip devices to be automatically redirected to the backup server2 IP address.
Could I do something like this with the Rage4 service recently advertised here???
Is there any easy way to make this happen??
