Hi Is there any way to do transfer on-hook with the Yealink T26/T28, 3CXPhone and 3CX V9? What I mean is User A has a call on line 1, they then put line 1 on hold and call User B on Line 2. User A then hangs up and expects the calls on Line 1 and Line 2 to be joined up. Or alternatively they then press the call transfer button and it should then join the calls up. Is this possible?
