QSIG-BC services
The level of service of QSIG-BC (basic call) is the same as on traditional tie lines with the following
advantages:
– Caller and connected party number identification
– Voice call
Accounting
Each outgoing call on the QSIG trunk generates a Call Detail Record (CDR) with the duration of the
call.
Interaction between the different systems
An Alcatel-Lucent OmniPCX Enterprise Communication Server user can make a call on a public trunk
line located on another PBX through the QSIG-BC interface. In this case, the Alcatel-Lucent OmniPCX
Enterprise Communication Server performs external call restriction. In addition, for all incoming
QSIG-BC calls, if the party’s class of service is sent by the connected PBX, the Alcatel-Lucent
OmniPCX Enterprise Communication Server is able to differentiate calls originating from private
subscribers and public trunks, and react as follows:
– Calls originating from private networks are treated as internal calls in attendant queues
– Public calls are stored in the unanswered call directory
– For calls coming from the public network through QSIG-BC, a call overflow on no answer
or busy user can be processed either by the Alcatel-Lucent OmniPCX Enterprise
Communication Server or in the transit network, depending on configuration
QSIG - GF/SS
GF (generic function) and SS (supplementary services) are the service enhancements of QSIG-BC.
Additional services have been defined as part of the new standard. Those standards, as soon as they
are available, are implemented in the Alcatel-Lucent OmniPCX Enterprise Communication Server
proprietary network protocol.
The QSIG-GF provides name identification plus transparent features. QSIG-SS provides telephone
services such as:
– Calling line identification presentation
– Connected line identification presentation
– Calling/connected line identification restriction
– Calling name identification presentation
– Connected name identification presentation
– Calling/connected name identification restriction
– Generic functional procedures
– Call forwarding - unconditional
– Call forwarding - busy
– Call forwarding on no answer
– Call transfer
– Path replacement
– Call completion to busy subscriber
– Call completion on no answer
– Call offer
– Advice of charge
