CTI Route Point Status MIB

Hello,

I have been trying to locate a MIB that shows the status of my CTI Route Points in Call Manager. I believe the statuses can be Registered, Unregistered, or unknown. I found ccmCTIDeviceStatus 1.3.6.1.4.1.9.9.156.1.8.1.1.5 and tried using that however it shows all of them as 2 which means registered. When I know for a fact I have several that are in an unknown state. Anyone know what MIB I should be using?

Also if there is such a MIB that exist how do I associate the status of a CTI Route Point with the Route Point Name or Route Point DN (Directory Number)?

Thanks,

Larry
