Hello all,
 
 I think I have found a bug in version 1.5.final+git~20150528T173517Z~6a2fc5e0f7~64bit
 
 My scenario is the following:
 
 
 A ----> calls ---> B
 
 B ----> calls ---> C
 
 B ---> sends REFER to join A and C (attended transfer via SIP)
 
 
 The two calls are connected A is able to talk to C, but after a while, the call is disconnected.
 
 When the REFER message arrives, FS sends BYE message to B with cause "NORMAL_CLEARING" and after a while (about 10 sec) FS sends a BYE message to C with cause "ATTENDED_TRANSFER" and the transferred call is hung up.
 
 I assume, that those causes should be swapped. BYE with attended transfer to B and no BYE at all for C until the call is ended by the endpoints.
 
 Do someone have this issue, how you fixed it? Should I upgrade my freeswitch to a newer version?
