Drop-down list of countries and regions. For

by Country/Region

each country, there are two choices:

of the choices seems appropriate, use

 

ITU/Europe. You can also customize the

 

settings by selecting Add/Edit Country.

Codec Preferences

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.
