I have some demo gear from Cisco, and am trying to set up our demo environment, prior to ordering our production IPT gear. I've installed CUCM 7.1 as standalone (publisher only) and am able to register some of my demo gear IP phones, but others get this error when trying to register:
Registration rejected : security error
Things I've checked:
- I've checked the 7942 and 7965 IP phones, and the security setting is set to non-secure.
The two phones have IP's, and have the call manager information correctly.
- I have phones that are working, they have the same config
- I tried resetting the phones to the factory config also.
- I've rebooted the Call Manager as well.
I've done some searching on CCO, and am not able to find any good guidance on what I could try next....
Any help would be appreciated.
