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? -- Tomáš Boros
