ATA 186 - Device is not trusted

[Carl.Mayne-Wheeler]

morning all,

I have upgraded some ATA's to the latest 3.02.4 and when registered to CUCM 7 it shows that the "Device is not trusted". Does anyone have any ideas why this is?

Thanks.

Hi Carl,

This topic has been covered before.

Note that the same applies for the ATA.

Many thanks for this.

Still confused as to why a Cisco product wouldnt be deemed as trusted though...

The ATA, along with VG248, do not support media and signaling encryption as they are older products. Most other voice endpoints do support that criteria and can be configured to be "trusted" endpoints.
