Hello,
registration of some 9971 phones in a fresh CUCM 8.0 environment fails constantly. The phones ran without problems in another CUCM 8.0 before and have the "old" config still active (because they never registered to the new cluster). The log of the phones shows the following:
|
| 21:08:06 Updating Trust List |
| 21:08:17 Trust List update failed |
| 21:08:27 TFTP-Error : ram/SEPD0574CF62596.cnf.xml |
The phones get a dhcp lease and the xml config file is also available on the TFTP server; hosts can reach each other. It seems that they are stuck at the TFTP step of the boot process. I searched for this error and found some hints towards possible authentication problems (CTL List), but there was nothing special configured in the cluster before (unsecure profile, i.e.). Aside from this, I am not yet very familiar with phone security/authentication.
Any help would be greatly appreciated. Thank you!
Regards,
Dennis
