We have 3cx v15.5 and Yealink T27P phones latest firmware. In this scenario our client had just transferred a call to someone and attempts to pickup another incoming call but ends up picking up the call they just transferred. They use *2 to pickup a call apposed to *20*. This scenario only seems to work if the call being transferred is picked up, then it will work. Not sure if its the phone or the system that needs configuring. Thanks for any help. P.s. This works OK if they put the call on hold but not when transferring.
