Yup. The version currently shipped with UCCX7.0.1 is WFM8.2.3.
The next one, WFM8.3.3 supports the following
UCCX v5.x, 6.0, 7.0
UCCE v6.x, 7.x
Just to clarify: Calabrio WFM does not "ship with" CCX 7. It is AVAILABLE for PURCHASE and can integrate with CCX 7.
CCX does not have a native scheduling function.
You have to purchase CCX Premium (SRP $1K + per seat) to even be able to use CCX WFM add on. There are other WFM vendors on the market with much better pricing and you would not need purchase CCX premium. Suggestions: Monet, Pipkins, Telrex, VPI
