On the phone, you can verify that the feature is enabled by choosing Settings > Device Configuration

two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one
or more of the following actions:

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of
external devices, cables, and connectors. The system will perform adequately when suitable devices are
attached using good quality cables and connectors.
