[cisco-voip] UCCX 10.6 | CUCM 10.5.2 | CAD Extension out of service

[Ryan Huff]

Has anyone been noticing that in this environment (UCCX 10.6 | CUCM 10.5.2 | CAD); extensions will sometimes report as OutOfService (and subsequently cause CAD login issues) when in fact, the phone is registered, associated to the jTAPI/RMCMSubsys user, has CTI Control enabled (and is setup correctly in all other respects)?

What seems to resolve this issue for me; is to super copy the phone to a fake mac address, delete the original and then re-mac the newly created device. Doing a cluster reboot seems to address this as well.

This is a new 2 cluster build. Everything about the phone seems to function fine within call manager when CAD is having a login issue. I've changed the addressing mode on the phone (and CTI ports) to ipv4 only, turned JAL off on the phone. Just really odd and not very easy to define.

I know CAD is near death and Finesse is the future, but I have to support CAD in this scenario.

Thanks,

Ryan
