Denying/ blocking a call
When the snom 320 signals an incoming call, you have the option
to deny the call with “Deny”.
If you press “Deny All”, the caller will be placed on the deny list
and will always be denied automatically. If “Deny All” is not displayed,
it is switched off in the settings. You can enable it via the web interface
(“Deny All” feature).
Adjusting the volume
In idle state or while making a call, you can use the
keys to increase or lower the volume of the audio device (casing speaker,
handset, headset) you are currently using.
