That description is still pretty vague? What is an Event Socket application, which has nothing to do with sip and sip transfers, that&#39;s a FS protocol.<br>

<div style="word-wrap: break-word;">I have two phones (Polycom) and an event_socket application, all of which are using a SIP proxy for call routing.  The first phone calls the second phone.  The second phone then attempts to transfer the call to the FS/event_socket application by first placing the call on hold and then calling the FS application, followed by a consultative transfer.  The REFER dialog occurs between the two phones and an INVITE w/Replaces is sent to FS.  The transferred call leg appears to be answered by FS and the application receives a uuid_bridge event with the UUID of the new call leg.  The problem that I see is that the original call leg, created when the user called the FS application to announce the transfer, does not get canceled by FS and subsequently does not send the BYE back to the Polycom.  Is there something that I need to do at the event_socket application to complete the transfer?  I&#39;ve tried killing the UUID associated with the first call leg as well as issuing an &quot;answer&quot; command to the transferred call leg UUID, but no luck.<div>

<br>FS gets refer+replaces all the time, if it&#39;s the one where the dest is on another box (aka the nightmare xfer that you should see references to in the debug log if so) then it will not complete until that far end call is answered.<br>

I&#39;m having a problem with attended transfers where the destination of the transfer is a FreeSWITCH based application such as FSComm.  (It should be noted that in my setup the phone performing the transfer and the caller which is being transferred are parties of another SIP server.)  What I see, from a SIP signaling standpoint, is that after FreeSWITCH receives and acknowledges the INVITE w/Replaces it does not terminate the initial call leg by sending a BYE to the transfer controller.  From the FreeSWITCH application side, FS still thinks that both the initial call leg and transferred call leg are active.  I experimented with trying to explicitly terminate the initial call leg by using uuid_kill, but this caused FS to kill all legs of the call.  Is there a specific action that the application must take in order for the transfer to complete?<br>
