Hi, We have a couple lines that need to be available 24/7 and our power supply is not very reliable. On power outages we can keep 3cx running for about 30 min before temperatures get too high (no cooling when on batteries). Our current procedure is to call our phone provider and ask them to set up forwarding... but sometimes it takes them a couple hours to get it done. Is there a way to forward incoming calls to a cell phone when the 3cx server is unavailable? can this be configured on the gateway? we are using a Patton 4960.
