Hi, A relatively complex (for me) 3cx implementation - v8 with 2x Patton 4 port gateways connected to PSTN. The business uses DR for Day, and a different DR for night. The night DR's cascade, because 3 different departments have different hours. That, we are able to configure for. The crunch is Wednesday, 1200 to 1300. There is a staff meeting (all departments, all employees) - and they want/need a DR to handle this. Configuring the DR is no problem, but at the moment the only way I can see to configure the incoming ports on the Pattons is to have an onsite admin go in at 1200 and change the "connect to DR" for each of the 8 ports. And then do it again at 1300. That's 16 changes :-(, manually. Can someone think of a more efficent way? Thanks, Les.
