What can I do if the volume of softphone calls is automatically lowered in the Windows volume mixer?
(This solution is available from XPhone Server version 8.0.512, for remedy in earlier version please contact support).
Remedy is a parameter which can be set centrally on the server side. By configuring the parameter, the registry key is ignored.
Set this as follows in the admin interface under Telephony > Gateways > SIP > SIP Gateway > "Parameter sets for lines" > edit used parameter set (default here is "Standard").
Parameters: SoftphoneClientConfig
Value: PUBLIC/EnableAudioDucking||false
Note: If multiple parameter sets are in use, you have to find the parameter set used for the lines concerned and add the parameter here.
