Trunk-to-Trunk Transfer
This section contains instructions to allow or disallow trunk-to-trunk transfer at
each extension.
If trunk-to-trunk transfer is disallowed on an extension in a private network, the
extension cannot transfer an outside call to a local system trunk connected to the
PSTN. See the Network Reference for more information.
Trunk-to-trunk transfer may only be performed on ground-start trunks and
loop-start trunks with reliable disconnect. As of Release 4.0, trunk-to-trunk
transfer may be performed on BRI, Tie lines, PRI, ground-start trunks, and
loop-start trunks that have reliable disconnect.
Trunk-to-trunk transfer is factory set to disabled and may be enabled for a specific
extension. Single-line telephones are restricted from completing a trunk-to-trunk
transfer.
Planning Form Instructions
