I want one extension (lets say x100 for example) to be shared by all phones. If a user answers the call and if a second incoming call comes in, I want all phones to ring again (including the extension that answered the first call). Is that possible?
When I configure x100 to be on all phones and a user answers x100, all new calls route to that extension that answered the first call and do not ring on all the other phones.
I have also tried chaining a bunch of DNs together, for example 100 forwards to 101, if busy x101 forwards to x102, etc.. Then I overlaid these extensions on all phones, however with this configuration if you answered the first call, new calls will not ring in to you, just all the other phones.
