- When starting the capture, make sure that you select "Capture
packets in promiscuous mode", otherwise only packets coming to and
leaving your laptop will be captured and not everything flowing though
the hub.
- Make sure you are connecting to a hub and not a switch. Otherwise
the capture approach has to be changed.

However, when I attach the notebook to a hub with a IP Phone attached on another port, strange thing happens. The Wireshark could capture packets except those of SIP and RTP related protocols (ex., I ping the IP Phone from the notebook and the packets of ICMP echo request and reply can be captured). No capture filters has been assigned in the Wireshark.
