Customer has a Unity Connection server connected to two different CUCM clusters. Existing system is set up with the phone systems including the AXL setup.
We are upgrading and virtualizing by doing a parallel build and will then use COBRAS to migrate.
After the new system was built, we set up one of the CUCM clusters, and configured it for AXL, and it was fine. The second is being a problem.
The setup to the second cluster fails on the AXL setup. I get a very cryptic error message that says "Failed to send message to remote AXL server. Please check error log for more details." Doesn't say what error log, and doesn't say on what device. I've dug around in the Unity Connection logs, and found nothing helpful. CUCM has a little more. I see the AXL request coming in, but for some reason, the query itself never does.
I've restarted the AXL service on CUCM, reset passwords, verified permissions, and cannot figure out what the problem is. There is one indication of a similar problem 5 years ago on a forum message, but that solution wasn't helpful for this situation. Google offered nothing else either.
Since it works on one CUCM cluster (the v9 cluster) and doesn't work on the other (the v8 cluster), but the existing system works with both, I'm completely baffled as to why it's not working.
Any clues would be appreciated.
