During troubleshooting it is useful to have access to the SIP flows  between SBC and BTTrade and Carrier

To get these the log settings need to be edited to change the default Voip Debug to Detailed from Basic

note make sure to put back when investigations are complete

SBC Utility Syslog Viewer

The SBC comes with a syslog viewer tool which is a windows application to help in analysis of the logs.

This can be found in the Utils folder on the BTExtranet as a self installing file AudioCodes-syslogViewer-setup.

Once this has been downloaded and installed if run up will see the initial dialog box.

From here in file menu choose connect or hit the chain icon and then enter the IP address of the SBC to connect to.

Once done hit connect and will start to see syslog info in the application

From the Tools menu select SIP flow or hit the i icon this will list the SIP flows and provide a diagram with the individual message details  

This is the most useful tool in debugging the SBC and will work even when using TLS where Wireshark will not.
