I want to slightly increase call volumes universally on our 4400, i.e. when a user picks up the handset and answers a call, the volume should be slightly higher than it is now.
I am not very familiar with the options located under System -> UA Set - Audio Parameters. Can anyone advise how to change correctly?

They already have this capability, the problem is that the maximum gain is not really loud enough for people using headsets in the busy call centre environment. I'd like to be able to give them enough room to turn it up or down if they need to. At the moment the majority of people just have the volume on max all the time and still struggle to hear sometimes.vad wrote:Specific telephone services - check item "Adjust audio gain". In this case each user can adjust level in handset with "+" and "-" keys.
Thanks, I found this page in the OmniPCX help. I'm not clear on which parameters need changing to achieve what I need though.zanex wrote:GBD/html/Audio_Parameters.html
Test to a like device it digital to digital
The most likely candidates seem to be Speaker Class 1-4 and the Digital Send Gain under Audio Paths - UA.
For speaker classes 1-4 I am not sure how the 7 levels relate to each other, and also whether increasing by 1 unit = an increase of 1 dB? Or are the numbers arbitrary?
I can test this out of hours but if anyone wants to share the benefit of their knowledge in this area it would be most appreciated!

it would be Audio paths - UA - would be across the all UA
Assuming that you are using a 4035 it would be a class 2 device.
If you are using a headset key i would adjust Hands-free Class 2
If you are not i would use speaker class 2
If you just wanted to increase the volume i would perhaps adjust Audio path in reception.
Each of the 7 levels represent the 7 volume adjustments availble on the handset
"Each of the levels 1 to 7 contains a decadic value between 0 and 255 which corresponds to a certain value of the gain in decibels"
As sound volume is measured in dB which is Logarithmic an change on 1dB represents a change of ten fold (base 10) with 0 being the reference. Gain is a way of expressing the change in dB (postive and negative), this is done to keep the number resonable otherswise the numbers would be massive.
Hands-free Class 2
Level 1 : 2 input source * 10^2
Level 2 : 3 input source * 10^3
Level 3 : 5 input source * 10^5
Level 4 : 8 input source * 10^8
Level 5 : 13 input source * 10^13
Level 6 : 22 input source * 10^22
Level 7 : 37 input source * 10^37
In this cirumstance Alcatel has only allowed values 0-255 i am not sure if this is scaled or not so potentially the values represented above could be incorrect but i thought that it would help illistrate the point
If i have made any mistakes please correct me
