Hello together,

since I have no notion from the whole subject still at all, I do not know unfortunately also, for which I must look.
Thus I would be pleased, even if their so would continue to help to me.
My telephone/Internet hardware consists at present of a Vodafone Esaybox 602.

Now I need a new similar festnetz telephone. I white already which it to be able to do is. Since I am sometimes terriblly lazy would not always like I to rise if I straight at the computer sit, but the discussion at the computer with a Mauskllick to much rather accept and the Headset than speech set, attached at the PC, to use.
Does that know the EasyBox of alone?
Or do I need a telephone the fact that additionally to the voice grade channel to a free LAN haven is hung and then by an appropriate software can be headed for?
I hope I could make understandable, for which I am.

Greetings
Hummel

Edit: Also over or other key word I would be pleased, so that I must search white according to which I.

After a longer discussion with Vodafone sihc the whole little clarified.

easyBox does not have the possibility the call which is received over the fixed net by LAN to the computer further to lead.

Does it give sowas? Or with at present actal IP telephones is standard?
