Got a two controller cluster setup, with a MAS NuPoint. The NuPoint is "homed" to controller A. MWI works perfectly for any/all phones on cotnroller A. However, if a voicemail is left for someone on controller B, the MWI only stays on for 8 hours. Which to me means that the Callback Cancel timer is turning off the MWI. I have verified that the HCIReroute HG on controller A is set with the same COS as the NuPoint ports. Amy I missing or forgetting something? Why is controller B's Callback Cancel timer not being ignored like it should?
