Changing Trunk-To-Trunk Transfer Status - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Changing Trunk-to-Trunk Transfer Status

Changing Trunk-to-Trunk
Transfer Status
Beginning with Release 3.1, the system includes an option to allow or disallow
trunk-to-trunk transfer for each extension. Trunk-to-trunk transfer is the
transferring of an outside call to another outside number. When trunk-to-trunk
transfer is allowed, there is a risk of toll fraud.
Use this procedure to enable or disable trunk to trunk transfer at one or more
extensions.
Planning Guidelines
!
SECURITY ALERT:
The default setting for all extensions, including voice messaging (VMI)
ports and remote access barrier codes, disallows trunk-to-trunk transfer. If
you elect to enable this feature at an extension, consider the risk of toll-
fraud abusers obtaining access to your system and calling out of the
system using this feature. For more information about protecting your
system from fraudulent toll charges, see Appendix A, "Customer Support
Information."
Valid Entries
Enabled, Disabled
NOTE:
A single-line set can never perform a trunk-to-trunk transfer unless it is plugged
into a port administered as a VMI port.
