Hello There was allready a Request to this: https://www.3cx.com/community/threads/add-signaling-method-building-up.48480/ I have many Customers who need a Signalising-Method in Ring Groups like this: 1. Ringing on Agent 1 2. after 30 seconds, Ringing on Agent 1 & 2 3. after 60 seconds, Ringing on Agent 1, 2 & 3 etc. I can build this with multiple Ring Groups like this: Ring Group 1 = Agent 1 (destination if no answer: Ring Group 2) Ring Group 2 = Agent 1 & 2 (destination if no answer: Ring Group 3) Ring Group 2 = Agent 1, 2 & 3 But the Problem there is, that when the Call is forwared from the Ring Group 1 to Ring Group 2, after the defined time, there is an interruption on Ringing about one Second. So now with the constellation from above if nobody take the Call, the Agent 1 has three missed Calls from this one Call. This ist not nice. But the big problem is that when for example, Agent 1 answer the Call after 30 seconds where the call goes to Ring Group 2, who i have the second interruption, its possible that i lose this Call on this Extension. Please implement this Feature. This would be easy. For example with an Option in Ring Group who i can set a time after the Call will ring also on an other Ring Group. Or remove the interruption between the transfer to the next Ring Group and show it as one call if a Extension is in multiple Ring Groups. I hope you understand this. My English is not perfect.
