Maintenance > Tools > Network utilities > DNS lookup
) to
assist in troubleshooting system issues. The SRV record lookup includes those specific to H.323, SIP,
Unified Communications and TURN services.
Unified Communications and TURN services.
Note that performing the DNS lookup from the VCS Control will return the view from within the enterprise,
and that performing it on the VCS Expressway will return what is visible from within the DMZ which is not
necessarily the same set of records available to endpoints in the public internet.
