Wireshark · Wireshark-users: [Wireshark-users] No H.225 (H.323 messages) in "Decode as"

[Gregory ESNAUD-FREE <gregory.esnaud@xxxxxxx>]

Hi there,

I've got a problem on Wireshark (0.99.5). I realize some packet capture 
on a voip call, and would like tag packet as H.225 messages... but the 
decode as interface don't bring me up H.225 category:

Could you help me?

Thx,
