I have a UC320 on 2.2.2 and am getting complaints that, when dialling out, the recipient has difficulty hearing the caller. This only happens with calls over SIP and not with calls over FXO. Is anyone aware of any way to raise the gain on the SIP trunk? If not, does anyone know of a way to easily change the gain of handsets?
Thanks for your post, One question, do you have an fxs connected phone on your UC320W, please try a SIP call with the fxs port and confirm the far end receiving volume. Confirm if the volume is low also.
I looked through the PMF files and we have an phone volume input gain but I will need to create one for phone output gain, there are 3 setting options, handset, headset, and speakerphone.
Speaking of that, when a SPA50x phone is configured as SIP client, it is possible to change input gain for handset/headset/speakerphone individually using the web interface. When the phone is connected to an UC320, the gain settings are displayed but cannot be changed since I cannot change to admin mode. Is there any way to adjust these parameters when the phone is connected to an UC320?
