QSIG B Private Networking

•QSIG Centralized Attendant Service (CAS)

The calls that cover from a QSIG CAS branch to main are not treated as QSIG-VALU Coverage calls. This is because calls covered to “attd” (administered as a coverage point on a Coverage Path form) do not utilize Remote Call Coverage table and QSIG-VALU Call Coverage is supported only for coverage points associated with Remote Call Coverage table. The implication of this is that the attendant on the main will lose QSIG-VALU Call Coverage display information and QSIG Path Replacement will not be invoked after the call is answered by the covering attendant.

•Coverage of Calls Redirected Off-Net (CCRON)

If both QSIG-VALU coverage is enabled and CCRON is enable, the QSIG-VALU coverage will have a higher precedence then CCRON.

•Privacy - Manual Exclusion

With Call Coverage feature, when the principal user bridges onto a call that went to coverage and has been answered at the coverage point, the user is not dropped when Privacy - Manual Exclusion is activated by the Covering user.

With QSIG-VALU Coverage, if the Principal bridges on the call after the remote covering user has answered the call. then the remote coverage user stays bridged until the call clears or the covering user goes on-hook.

•Simulated Bridge Appearance (SBA)

With QSIG-VALU, maintaining SBA for Principal user will be based on the administration of the field “Maintain SBA at Principal” on the System Parameters

-Call Coverage / Call Forwarding form.

•Temporary Bridge Appearance (TBA)

Same interaction as Simulated Bridge Appearance.

•AUDIX / Centralized AUDIX

AUDIX is usually specified as the last coverage point. When a call is routed to AUDIX (local or remote centralized place), the TBA (Temporary Bridge Appearance) is not maintained for the Principal user (i.e. the Principal user can not bridge on to the call after it routes to AUDIX).

For the last coverage point, which do not require control at the Principal user’s PBX, the QSIG-VALU Coverage shall route the call as QSIG Diversion by Rerouting instead of QSIG Diversion by forward-switching and let the remote calling user’s PBX route the call directly to the remote covering number. If the Rerouting PBX indicates failure, then the Principal user’s PBX (i.e. Served User’s PBX in terms of QSIG Diversion) shall revert to the normal QSIG-VALU Coverage handling. The advantage of this approach is that it saves the trunk resources and provide path optimization without QSIG Path Replacement.
