Drop-down list of countries and regions. For
each country, there are two choices:
Standard and VoIP. The VoIP choice
provides rings and tones that are different
from conventional telephone service. If none
of the choices seems appropriate, use
ITU/Europe. You can also customize the
settings by selecting Add/Edit Country .
You can prioritize the codecs
(COde/DECode) from 1 to 3. The first priority
default is G.711u (North America best voice
quality). Other choices are G.711a (outside
of North America) and G.729. G.729 uses
less bandwidth and is a good choice if you
have a connection below 160kbps and/or
heavy data traffic. If you select G.729 for
priority 1, leave priorities 2 and 3 blank.
