Transfer — Trunk-to-Trunk 
20
To administer Trunk-to-Trunk Transfer system-wide, complete the 
Feature-Related System Parameters screen. To restrict Trunk-to-Trunk Transfer 
on a trunk-group basis, assign COR-to-COR calling-party restrictions on the Class 
of Restriction (COR) screen. To allow individual users to control Trunk-to-Trunk 
Transfers, assign capabilities on the Class of Service (COS) screen.
Considerations
Trunk-to-Trunk Transfer is particularly useful when a caller outside the 
system calls a user or attendant and requests a transfer to another outside 
number. For example, a worker, away on business, can call in and have the 
call transferred elsewhere.
Transferred trunk calls can be administered to receive either music or 
silence.
Some central office (CO) trunks do not signal the PBX when the CO user 
disconnects from a call. The system ensures that incoming CO trunks 
without Disconnect Supervision are not transferred to outgoing trunks or to 
other incoming CO trunks without Disconnect Supervision.
An attendant-assisted call connecting an outgoing trunk or incoming trunk 
without Disconnect Supervision to an outgoing trunk must be held on the 
console. The system does not allow the attendant to release the call. The 
attendant can, however, use the Forced Release button and disconnect all 
parties associated with the call.
If a user has connected two outgoing trunks or an outgoing call and an 
incoming call without Disconnect Supervision, the user must remain on the 
call. Otherwise, the call is dropped. An incoming trunk with Disconnect 
Supervision can be connected to an outgoing trunk without the user 
remaining on the call. An incoming trunk can also be connected to another 
incoming trunk without the user remaining on the call if one of the 
incoming trunks has Disconnect Supervision.
Interactions
Attendant Lockout
Attendant Lockout does not function on Trunk-to-Trunk Transfer.
Call Vectoring
Station control of Trunk-to-Trunk Transfer does not affect routing of 
incoming trunks to a VDN that ultimately routes to a destination off-net.
A route to a number off the switch does not require you to enable 
trunk-to-trunk transfer.
