Why my Avaya 9641GS was working but now it does not?
- V
  Victor McmillanAug 26, 2025
  If your Avaya Telephone was working but now it doesn't, check the connections between the deskphone, the power supply, and the power jack to ensure there is no loss of power. If power is fine but there's no dial tone or the call appearances/feature buttons don't work, check LAN continuity from the call server to the deskphone and back. Verify that administration settings for LAN equipment between the call server and the deskphone haven't changed, and that no one has altered the deskphone settings locally.

Why the audio quality is poor on Avaya 9641GS Telephone?
- M
  michaelmontoyaAug 28, 2025
  If your Avaya Telephone's audio quality is poor, try a different Call Quality setting under the Audio Parameters section. Check whether packet loss, or jitter delay is causing this problem, by eliminating or minimizing both. Verify which trunk is causing the echo, and check the trunk’s Trunk Termination parameter on the call server.

What to do if Avaya Telephone has sudden silences or garbled speech?
- C
  Chad DanielsAug 28, 2025
  If you experience sudden silences, gaps in speech, or static/garbled speech on your Avaya Telephone, it could be due to jitter, delay, or dropped packets. You can have the user provide diagnostic data by invoking the Network Information feature under the A (Avaya) button on the deskphone. One or more Quality of Service (QoS) features should be implemented in the network. It may also be due to improper non-Category 5 wiring, replace non-Category 5 wiring with Category 5 wiring.

  sriosAug 30, 2025
  If you hear an echo on your Avaya Telephone headset but not on the handset, the issue might be an improper headset adapter. Replace the adapter with Avaya’s M12LU or 3412-HIC adapters. The M12LU is recommended, since it supports Automatic Gain Control.
