I am troubleshooting a voice call and I applied a SIP CallID filter, the problem is that I don't see the TCP retransmit anymore in my capture for that specific call ...
I have a friend that has Wireshark 1.10.5 and it is working for him but I am on the newer version and it does not show the TCP retransmit .
Anyone has any hint to give me? :)

By default in recent versions of Wireshark the TCP dissector does not pass "error" packets (such as retransmissions) to upper layer dissectors. This is because these error packets tend to confuse the upper-layer protocol dissectors (because they see the same data more than once).
If you want the old functionality back you can disable the TCP preference
