The dumpcap/tshark executables do not appear to flush there buffer when exiting
as the wireshark command does. Attached is the wireshark log. If you filter on
SIP message only you can clearly see the receipt of a BYE message.

I have a second capture using dumpcap conducted at the same time (which I can't
seem to attach to this bug) that has no BYE message within it.

I reported finding this issue using tshark in bug 1875 and was recommend to try
dumpcap instead. At first it seemed to work, but these two logs shows there is
some type of discord between the two tools. 

Can someone explain why on seems to work and the other doesn't?

I an send the second attachement from dumpcap to whomever needs it.
