My initial call flow is as following

2.      180<--------|
3.      200<--------|

4.      ------------>ACK

5.     *************|-------------->INVITE
6.     *************|<---------------180

7.     BYE------->|

8.     Retransmissions of BYE

9.     *************|<----------------200 OK

10.   200(bye)<---|

Now Leg B remains hanging... Shouldn't FS have killed it since legA is dead.

On Application I get Channel Hangup on 200 bye. leg B call is generated using bridge command with hangup_on_answer = TRUE.
