[T21P] Problem with Blind Transfer

[jjnet]

Hi,

We have almost exactly the same issue with Yealink Phones and 3CX Call Queues. As an example the Yealink T46GN is not releasing call on blind transfer until answered/timed out at the other extension and this seriously delays new queue calls from reaching the Agent (20-30 seconds sitting idle)

This is what happens currently:
A calls B
B blind transfers to C (using method: TRAN->extn->TRAN)
B does not release the leg of the call until C answers (the display on the phone shows the call has left, however 3CX still has a leg open to phone B until A and C are connected)

This is what should happen:
A calls B
B blind transfers to C (using method: TRAN->extn->TRAN)
B releases the leg of the call when TRAN is pressed a second time

The behaviour only seems to occur with Yealink phones, i have tested using a Snom 870 and the 3CX SoftPhone which release the call straight away and the next call queue can come straight to the Agent.
