Step 2

Step 3
Click Generate PRT for Selected to collect PRT logs for the headsets used by the selected phones.

• Eliminate potential sources of radio interference between the headset and the base such as large
metal or glass surfaces and other DECT devices.
• Make sure that the headset bases are not too close to each other. For more complete DECT headset
deployment and density information, refer to the Cisco white paper,
