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 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 vector
directory number (VDN) that ultimately routes to a destination off-net.
A route to a number off-switch does not require you to enable trunk-to-trunk transfer.
•
Tenant Partitioning
— Station control of Trunk-to-Trunk Transfer is prohibited between trunks in different tenant
partitions if those partitions are restricted.
