We had tried the existing methods of updating the display on attended transfer using SIP INFO and SIP UPDATE but these do not work with Bria, the INVITE was the only method we could get to work.</p>

<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">When performing an Attended Transfer to a Call Center Queue if the agent answers at the same time the transfer is completed the call is dropped and both the agent and transferee are sent the SIP message Destination_Out_Of_Order.
The call disappears from active calls\sessions but still exists as a member in the Call Center Queue, the only way to clear this call is to either manually delete the call from the queue members table in the backend FS database, reload the Call Center module
or restart FreeSWITCH.</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">It's very difficult to time correctly, even when attempting to answer and transfer the call at the same time this only occurs in roughly every 1 in 20 calls. However, in call centre environments where calls may be regularly
transferred into queues this occurs frequently. Training agents to use the appropriate transfer method is one approach but is not fix.</p>
<p style="margin-top:0; margin-bottom:0"><br>

<p style="margin-top:0; margin-bottom:0">Is this a known problem?</p>
