I am attempting to set up a queue for our after-hours on-call workers. Because I want it to ring their mobile devices first I created a 2nd extension for the users with only the mobile number configured. If I set it to "Ring my mobile simultaneously" the calls ring through, but the caller ends up in the voicemail of the first user in the queue. I am looking to have it do a rebound so that the user can confirm the call before the system will connect the caller. Since there are no phones registered for the user if I don't have the "Ring my mobile simultaneously" option enabled the system says there are no agents available and hangs up. This is currently working fine on our old Asterisk-based system, but I am having a hard time replicating the configuration on the 3CX side.
