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.

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 

Enabled, Disabled

A single-line telephone can never perform a trunk-to-trunk transfer unless it is 
plugged into a port programmed as a VMI port.
