Hello We have a location with 2 Fanvil door phones. They currently ring at reception 24/7. We need to route them to a different ring group based on the office hours. Sounded simple.... We had a cyberdata door phone before, those had on board scheduling, but they died out too frequently. This FanvilT20 does not support hour/based dialing. How can we tackle this on the PBX? Since it's an extension, we can´t use inbound rules. all ideas and suggestions are welcomed.
