Table 10: Some Error Conditions in Operation of 4600 Series IP

Telephones (continued)

Condition	Cause/Resolution

The telephone works, but the audio quality is poor, specifically:

the user hears echo when speaking on a handset.

CAUSE: Echo from digital-to-analog conversion on your Avaya media server trunk.

RESOLUTION: Verify which trunk is causing the echo, and swap the trunk’s Trunk Termination parameter on the PBX.

the user hears echo on a headset, but not on a handset.

CAUSE: Improper headset adapter.

RESOLUTION: Replace adapter with Avaya’s M12LU or 3412-HIC adapters. We recommend the M12LU, since it supports Automatic Gain Control.

the user is on Speaker and hears no echo, but the far-end hears echo.

CAUSE: Room acoustics.

RESOLUTION: Ensure that there are six inches or so of blank space to the right of the telephone. If that is insufficient, use the handset.

the user experiences sudden silences such as gaps in speech, or static, clipped or garbled speech, etc.

The 4612 or 4624 IP Telephone works properly except the phone does not ring.

CAUSE: Jitter, delay, dropped packets, etc.

RESOLUTION: One or more Quality of Service (QoS) features should be implemented in the network. See Chapter 3 of the 4600 Series IP Telephone Installation Guide.

CAUSE: Improper non-Category 5 wiring.

RESOLUTION: Replace non-Category 5 wiring with Category 5 wiring.

CAUSE: The Ringer Off (RngOF) softkey feature has been activated.

RESOLUTION: Use the softkey Menu option to access the RngOF feature. A downward-pointing triangle means the Ringer is off. Ensure that the triangle points up. Also, check the Volume setting on the telephone. Finally, do a self-test on the telephone.
