Analog phone volume is low on VG350

[Lin Zhu]

Hi all,  one customer complain that analog phone volume is pretty low, it connects to VG350,  can we increase it by CLI?

thanks.

There are two things related to audio, output attenuation and input gain. OA is inversely proportional to the value your configure i.e. a negative value will increase the volume and a positive will decrease it. Input again is proportional, positive value means an increase and negative means a decrease. You will tweak OA if you want to +/- out audio, IG would be +/- in audio. Both values in decibels.

thanks Nipun, 

I put IG to max value, but in-audio seems no any increase.

is there anything else I need to check?

voice-port 2/0/11
