Sipura Spa-841 - Mute feature?

Archived from groups: comp.dcom.voice-over-ip (More info?)

Hello,

I have studied the .pdf manual in the Sipura.com website
about the 4 lines Sipira Spa-841 but I'm not able to understand
if I when I receive a call I can click the button "mute" and put in
hold in that manner the call, so he cannot hear my voice and
I can hear it. The Mute feature is not the "hold" or similar feature
where I do not hear the caller if talk or make comments.
I need the mute feature, is included in this sip phone or not?

Let me know thanks
