Ringing on second call - 3CX

[Chris Barron]

I have a workaround fix for this, as follows.

Register a second line to the phone, to illustrate, label it "overflow'

Turn off call waiting on the first line and allow secondary calls to route to the overflow line (Divert/ring group/group hunt)

Rather than configure the second line with its own key, configure it as BLF with ring.
