Delegated
credential
checking
Controls whether the credential checking of
TURN server requests is delegated, via a

determines which traversal
zone is used.

mechanisms (local database or H.350 directory
via LDAP) on the VCS performing the
authentication challenge.
On

traversal client.
The default is
