Security on IP Phones

[Gerardo Fajardo Perez]

Hi,

I have already installed a CTL Client and phones do not register with de CUCM while applying Security (security mode cipher).

Following steps are done:

- CUCM in Mixed Mode (Cluster Security Mode 1)

- Cisco CTL Client installed with two Tokens

- Reset CUCM

- Device Security Profile´s phone  with a Secure Profile

What do you think would be the problem ?

Thanks in advance

Fix it !!!

Have to reset Call Manager and TFTP in Serviciability, not just CM in System.

Thanks a lot.

Glad you found it yourself and shared, the last step in the CTL client tells you to restart CCM and TFTP on all nodes.
