I have got a new CallManager 5.1 installation. Everything is set up. When I plug a brand new 7961G phone into network, it boots up OK but can not register - every 3-4 seconds it tries to register but the registration is rejected with the message "Registration Rejected: Error Mismatch". When going to Settings -> Status -> Status Messages I can actually see that there is no CTL installed on the phone, so it tries to get CTLFile.tlv file from the server but can not find it. The CTL file has to be installed during 5.1 installation process but obviously it was not. The cluster is configured for non-secure mode. Any idea how to sort this and make phones register??? Thanks a lot!
