6
Telephony Services client, only the transfer originator calling information is
delivered to the extension, not information about the original caller.
■ PSTN Trunk Transfer. The system permits trunk-to-trunk transfers of
inside or outside calls to non-local extensions, regardless of whether
system programming has prohibited trunk-to-trunk transfer. However,
trunk-to-trunk transfer does not work under the following circumstances:
— Trunk-to-trunk transfer is prohibited at the transferring extension and the
call is an outside call being transferred to a local PSTN line/trunk.
— The transfer originator is attempting to transfer an outside PSTN or
private network call to or from a loop-start line that does not have
reliable disconnect. All loop-start lines connected to networked systems
must have reliable disconnect.
If the problem persists, call the Lucent Technologies Helpline at 1 800 628-2888;
consultation charges may apply.
Transfer Call to Non-Local
Extension Does Not Return 6
Possible Cause: If a transfer to a non-local extension cannot be completed (due
to the extension being busy, for example), the transfer returns only when the call
was transferred manually and routed over tandem PRI facilities. Calls are not
returned under the following conditions:
■ The call is routed over tandem tie trunks or PSTN trunks that may be used
for less preferred routes
■ The system operator transfers the call using a DSS programmed for
transfer with automatic completion over PRI tandem trunks.
What to Do:
Review the routing for the call (see “Reviewing the Non-Local Dial
Plan and Routing” on page 3 for instructions), and check with the coordinating
system manager if necessary. If the call is routed over any tandem tie trunks or
over any PSTN facilities, or if an operator is using a DSS programmed for transfer
for automatic completion over PRI trunks, you have solved the problem.
If the call is routed only over tandem PRI facilities, call the Lucent Technologies
Helpline at 1 800 628-2888; consultation charges may apply.
