I'm using CUCM 7.1.3 and 2811 with FXO port as MGCP gateway. Each user is using softphone. When there is incoming call to softphone, the user complain that the sound is small. I've tried to increase the volume of softphone to maximum and increase the volume of headset to maximum. But the sound is still small. Is there anything to configure in CUCM or FXO port to make the sound louder?
Currently, i'm using default fxo port configuration. Please see the attachments.
insert loss using this command, so -1 turns the volume up and 1 turn the volume down. You can use
