Hi All, Thanks for your help as always. I have a CISCO 504G four line phone. I don't think the model is particularly relevant, just that it is a multi-line phone. Issue one: If line 1 is busy, I want new calls to be directed to line 2. If 1 and 2 are in use, ring on 3 and then line 4. I think this means call waiting will need to be disabled so that each will ring busy, enabling rollover. Also, I don't want lines 2, 3 and 4 to all ring if 1 is busy. I think I just use continue_on_fail=true and hangup_after_bridge=true, then route to Line 1, then 2, 3 and 4. Issue two: I have 6 phones in a call group and I need the call group to ring each phone like explained in issue one. I cannot for the life of me figure out how to "layer" devices to failover independently when dialed in a group. That is to say, when a call comes in it should be bridged to all 6 phones on the lowest available line button. Whoever answers first gets to call and all other lines return to ready state. Any thoughts would be greatly appreciated. Sean
