If you look at the packet dissections you'll see that there are packets related to signalling (ie. SIP, SDP, H225, H245, MEGACO, AIX or others), packets that carry media related to these calls (usually in RTP, sometimes others) and packets related to other traffic. Wireshark analysis gives you the option to have it find VoIP calls and show the related signalling, and/or even the media.
