Verifying lawful interception
From TBwiki
Applies to version v2.7
Installing ruby 'gem'
The Lawful Intercept filter script requires the 'json' ruby gem.
TMedia units (TMG800, TMG3200, TMG7800), provided by TelcoBridges, are now shipped with this 'gem' installed.
If you have older TMedia units, or if you are using your own host, verify that the host has the 'json' gem is installed:
gem list --local
If it is missing, it can be installed from a shell:
gem install json
