Setting Up QSIG VALU
Call Coverage
Steps
Begin
1 Enable the QSIG Basic Supplementary Services on the Customer Options screen,
page 6, described above.
2 Enable (enter y) Value-Added Lucent (VALU) on the System-Parameters
Customer-Options screen, page 6, as described above.
3 On a Trunk Group screen, enter y in the QSIG Value-Added Lucent field, page 1,
and sent b in the supplementary Service Protocol Option field, page 1.
4 Administer the System Parameters Call Coverage/Call Forwarding screen as
normal, with the inclusion of the following fields:
• Immediate Redirection on Receipt of PROGRESS Inband Information,
page 1 — Enter y to speed up redirection of subsequent coverage points or
call processing. This may be necessary in cases where coverage path
endpoints over non-Lucent switches are unavailable but the QSIG
networked switch (or the public network) sends PROGRESS messages
that delay the local switch from redirecting the call elsewhere. If the QSIG
network contains only DEFINITY switches, enter n.
• QSIG VALU Coverage Overrides QSIG Diversion with Rerouting, page 1
— Enter y to ensure that the "coverage after forwarding"
activation/deactivation defined at a user’s phone (via Station screen) takes
precedence over the system-wide "coverage after forwarding"
activation/deactivation selection (via the System Parameters Call
Coverage/Call Forwarding screen). With QSIG Diversion with Rerouting
active, the system-wide selection takes precedence unless you enter y.
See the examples in the following table: .
