Hi, We have setup a few clients on 3CX cloud with remote phones with no issues. Only problem is, if the internet goes down at the remote site, or if the 3CX Cloud server is offline, the remote client completely loses phone communication. I am aware of backup 3G/4G failover, but Is it possible to have the remote phones failover to a Patton gateway (connected to POTS lines) located onsite at client location? If not, is there another solution? Any help would be grealty appreciated. Thanks!
