Review the raw ISUP data packets when debugging applications. This feature, called data tracing, can be enabled or disabled using the isupmgr demonstration program, or it can be enabled or disabled in the ISUP configuration. Refer to the Dialogic® NaturalAccess™ Signaling Software Configuration Manual for more information.
When enabled, the raw data packets are sent to the ss7trace program that is included with the MTP3 product (including the ss7trace source code). Messages are presented as hexadecimal dumps with the source and destination pulled out for viewing. The first two bytes of each trace are the CIC for the message, and the third byte is the message type.
