An SS7 probe is a physical device to obtain signalling and/or bearer information from a telecommunications network, such as the PSTN or a corporate telephone system. The probe passively monitors the E1/T1 or SDH/SONET bearer channels, and extracts the signalling information for onward presentation to an application.
