Ring and Tone Configuration
When you select your country or region from the Select Ring and
Tone by Country/Region list on the Voice over IP page, the
appropriate tone and ring configuration information is entered
automatically.
If, however, you select Add/Edit Country from the Select Ring
and Tone by Country/Region list, the Ring and Tone
Configuration page appears. The settings initially displayed reflect
the ring and tone values of the country or region you have
previously chosen—or the default if you haven't changed it.
You must enter a name in the New Country field and then fill in
the remaining fields. These fields control the ring sound you hear
when your VoIP phone rings, and the tones you hear on the line
when you make a call. Consider customizing these fields only if you
are very familiar with the technical definitions of the ring tones.
To save your edits, on the Action list select
ADD_NEW_COUNTRY, click Save Changes and then Write
Settings to Flash and Reboot.

Click the arrow to select your country/region
from the list. The appropriate ring and tone
information will be entered automatically. If your
country/region is not shown, select Add/Edit
Country to display the Ring and Tone
Configuration page (see below).
You can prioritize the codecs from 1 to 3. First
priority default is G.711u (best voice quality for
North America). Other choices are G711a
(outside of North America) and G729 (uses less
bandwidth).
If you want to force the use of one codec, list
that codec only, and leave the second and third
boxes blank.
