Adjusting the volume

There are cases when a customer can be heard very quietly during a phone call and there is no way to increase the volume level on the telephone /softphone. Let's describe a way that can help in solving the problem:

1. Go to "System" -> "System file customization"

2. Open modules.conf for editing

3. Add to the end of the file

load => func_volume.so

Save the changes

4. Open the extensions.conf file for editing

5. Add the following code to the end of the file:

[all_peers-custom]
exten => _X!,1,Set(__DYNAMIC_FEATURES=vUp#vDown)
    same => n,Set(VOLUME(TX)=5)
    same => n,Set(VOLUME(RX)=5)
    same => n,return   
    
[add-trim-prefix-clid-custom]
exten => _.X!,1,Set(__DYNAMIC_FEATURES=vUp#vDown)
    same => n,Set(VOLUME(TX)=5)
    same => n,Set(VOLUME(RX)=5)
    same => n,return

[volume-level-control]
exten => up,1,NoOp()
    same => n,ExecIf($[ "${Vol}x" == "x" ]?Set(Vol=0)
    same => n,Set(Vol=$[${Vol}+5])
    same => n,Set(VOLUME(TX)=${Vol})  
    same => n,return
exten => down,1,NoOp()
    same => n,ExecIf($[ "${Vol}x" == "x" ]?Set(Vol=0)
    same => n,Set(Vol=$[${Vol}-5])
    same => n,Set(VOLUME(TX)=${Vol})  
    same => n,return

Save the changes.

6. Open the features.conf file for editing

7. Add the following code to the end of the file:

[applicationmap](+)
vUp => #1,self,Gosub,"volume-level-control,up,1"
vDown => #0,self,Gosub,"volume-level-control,down,1"

Save the changes

The default volume will be higher, the value is 5 instead of 0. If desired, the employee can dial #1 to increase the volume or #0 to decrease
