I have two DECT phones and three iphones connected to a 3CX server. When I try to transfer the call from the iphone to the cisco all is ok, but from the cisco to any other phone, it fails.
I selected on the page just one line per phone.
Am I missing something? When I click the transfer button it opens a new line (BTW, it takes long to make the second call) and then nothing more. I click transfer again but nothing happens, same with swap.
