if IOS5 uses the connection-less SCCP service SCCP-connection-tracking
cannot help you.
If it instead uses the Conection-Oriented SCCP service, you can take a
look at how RANAP and BSSAP put "interesting information" into the
SCCP data for the packet/connection.
(Beware that in order to trace calls SCCP needs the "Keep Track of..."
preference being enabled).
