Call volume goes up and down during the call. 1

[TelecomTony]

Hello,

System back ground
Main system is in a data center with 8 remote sites running G650's. All sites are connected via IP running G7.29. All ports on the network equipment are running 100 full duplex

Problem
I have 1 site that is having issues where the volume starts out fine but will fade up and down to the point where the agent is unable to hear the customer. The agent tries to adjust the volume on the phone so they can hear but it will go back up and she will have to turn it down.

Hardware
Avaya 2420 phones
Jabra 2300 biz headsets with and without an amp
Firmware on set is version 6

What we have tried
- we have replaced phones, line cords, cross connect, digital calls as well as moved them to entirely different area in the call center.
- if the agent switches to the handset the volume is fine.

The network group is not seeing any jitter, packet loss or any other network related issues.


Any suggestions on what may be causing this issue?

Thanks

Call jabra and complain, ask them for specific compatibility settings try plantronics or similar to see if that works , if you are saying the volume is okwhen talking on the handset you have really answered your own question.

The below are all settings in the 46xx settings file that you can play with , but i still think you should contact jabra as a first port of call , then try a different headset , upgrade the phones to the latest firmware , then read the lan admin guide get an understanding fro the below settings and logically change as required to see if improvement can be achieved

also these settings in the 46xx settings file.
