SIP packets are decoded in 1.12.3 but not in 2.2.0
I am currently using an older version of wireshark to support something for work. Version 1.12.3 (v1.12.3-0-gbb3e9a0 from master-1.12) I created a capture of a call scenario and I can see the entire call flow but my co-worker reviews the same file with the different version of wireshark(newer version) , the same SIP packets are not being decoded as SIP. What can be done so that they can see this SIP messaging decoded.
wireshark 2.2.0
Note that 2.2.0 is newer than 1.12.3, but it's far from the latest version - the latest version is 3.0.
