I have configured outbound with Transfer to IVR option. (First outbound calls customer and then switch call to IVR)
I want to know the techonlogy of using IVR ports in this situation. I mean, forexample I have working contact-center and I also try to use outbound with transfer to IVR could IVR use ALL of ports? Could some customer hear BUSY signal in the moment of shortage IVR ports?
