• Internal Automatic Answer (IAA)
If the IAA feature is enabled, QSIG SS-CC calls are not answered automatically.
• Manual Originating Line Service
A manual originating service cannot request QSIG SS-CC.
• Multimedia Endpoints
You cannot activate QSIG-CC towards multimedia data endpoints.
• Restriction Features
~ Class of restriction (COR): Any terminal that is Origination-restricted cannot
activate SS-CC. Any terminal that is Termination-restricted cannot have
SS-CC activated towards it.
~ Class of Service (COS): To invoke SS-CC, the ACB field on the Class of
Service screen of the calling terminal must be set to yes.
• Ringback Queuing
Ringback Queueing and ACB share the same button to indicate that they are
active. If the user has only one ACB button, then both features cannot be active at
the same time.
• Outgoing Trunk Queuing
Outgoing Trunk Queueing cannot be invoked after the calling party answers the
priority call back call and no trunks are available. The SS-CCBS and SS-CCNR
request cancels at both PBXs.

You cannot activate QSIG SS-CC towards a TEG extension, but QSIG-CC
requests can be activated towards a single member in the group.
• Uniform Call Distribution and Direct Department Calling
You cannot activate QSIG SS-CC towards a uniform call distribution group or a
direct department calling group extension, but you can activate towards a single
member in the group.
