It means that with SIP, all messages are sent as ascii text. Using a sniffer, it is very easy to read what’s going on. A typical message might be:

INVITE: sip:tom@howard.com SIP/2.0

With H.323, all this information is encoded into a more bandwidth effecient stream, and cannot easily be interpreted without software.
