Signaling System 7 (SS7)

Configuring an SS7 signaling gateway

ss7nmi debug-level command

The TAOS unit reports the VoIP call statistics in the output of the ss7nmi debug-level command. When the command is entered with the -soption, the results displayed include the number of release channel request (RCR) and release channel completed (ACR) messages sent with and without VoIP call statistics, and the number of unknown SS7 VoIP messages. In the following example, new statistics reported for IPDC VoIP calls are shown in bold type:

admin> ss7nmi -s

Statistics and error reporting on SS7 connections

The ss7asg -scommand provides detailed interface information about statistics and error conditions on SS7 connections. The output differs depending on whether errors are detected.

Note: The ss7asg -rcommand resets all the signaling layer statistics to 0 and updates the timestamp to the time the counters were reset.

Command output when no errors are detected

The following sample output indicates that no errors were detected in SS7 connections:

admin> ss7asg -s
