Your ability to use G.722 is limited to calling other phones that are
G.722, and they typically on when the call is pure IP. If the call
transits the PSTN then the phone can only use G.711 like the rest of
the legacy public phone network.

I know nothing about VoipTalk. If they allow you to call other VoipTalk
users via IP then you may enjoy wideband calls to them. Alternatively,
you may register a free account with some other SIP provider and start
making calls via SIP URI. This is the most common approach to achieving
wideband calling.

I wrote some guidance on doing just the
here:

Oh, yeah. I have a Gigaset A580IP with a couple of additional S67H and
SL78H handsets.
