Troubleshooting

Poor Audio Quality

Problem

Your user experiences poor audio quality.

Solution

• Unplug and reconnect the headset to the desired call device.

• If users experience poor audio quality with the Cisco Headset 560 Series:

Generate PRT for Endpoints on Unified CM

Use this procedure to trigger the Problem Reporting Tool (PRT) on the endpoints.

Procedure

Step 1

From Cisco Unified CM Administration, choose Device > Phone.

Step 2

Click Find and select one or more phones that the headset connects to.

Step 3

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

Step 4

Click Save.

Cisco Unified Communications Manager sends SIP Notify messages to remotely trigger the log collection on

the phone and upload it to the log server configured in the "Customer support upload URL" parameter.

• 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,

for the Cisco Headset 560

• Make sure users securely return their headsets to the headset base when the headsets aren't in use.

The Cisco Headset 560 Series reduces the DECT frequency when the headset is seated in the base.

• Lower the headset's DECT range and bandwidth in Cisco Unified Communications Manager

Administration. See

Headset Template Management, on page 17

Note

When you switch Cisco Headset 560 Series to Short Range or Medium Range,

users will not be able to roam as far from their base.
