Whats the impact - are you seeing any issues because of this? I doubt if it would impact anything, CUCM is just not seeing the device as trusted and this is informational only generally. If that's the case you can leave it like that.

But if you are seeing any issues post back with the symptoms.

From memory the Callmanager does a check against the device type and then displays Device not trusted.

There is nothing you can do about ,it is purely informational and is generally  not an issue as Terry says.

Dear Terry,

Thank you for your reply,There is no impact on any thing,however i am worried about security of the call that made from these devices.Because CUCM will consider as non-secure call leg.So is there a way to overcome

Thanks

Hi - this is not something we can set to trust or non-trust. It could be due to a certificate issue or for some reason Call Manager is not seeing it as a trusted device. Look at here:

Cisco Unified Communications Manager allows Security icons to be enabled by phone model on Cisco Unified IP Phones. The Security icon indicates whether the call is secure and the connected device is trusted.

If you are too concerned you can try a different (preferably a newer) firmware on one phone and see if it fixes. Additionally you can also try to factory reset one of the phone (not sure on this one but you can try).

A Trusted Device represents a Cisco device or a third-party device that has passed Cisco security criteria for trusted connections. This includes, but is not limited to, signaling/media encryption, platform hardening, and assurance. If a device is trusted, a Security icon displays and a secure tone plays on supported devices. Also, the device may provide other features or indicators that are related to secure calls.

Cisco Unified Communications Manager determines whether a device is trusted when you add it to your system. The security icon displays for information purposes only, and the administrator cannot configure it directly.

Cisco Unified Communications Manager also indicates whether a gateway is trusted by displaying an icon and a message in Cisco Unified Communications Manager Administration.

This section describes the behavior of the security icon for trusted devices on both the Cisco Unified IP Phones and in Cisco Unified Communications Manager Administration.
