How do I setup my S20 PBX for a secondary Hostname/IP and Domain for my VoIP provider? I am using Peer Trunk with 1-VoIP.
They have a primary and secondary server. The secondary is automatically used when there is a primary failure.
Do I have to set up two different trunks and manually change to the secondary? If so, that would be an ultimate pain. I'm hoping there are some settings that can be made to make the changeover happen in the S20 PBX, automatically, if there is a failure of the 1-VoIP primary IP.
