Setting Custom Tones and Cadences (optional). The Regional Parameters dialog box has a secondary dialog box
that allows you to customize DTMF tone pairs to create unique ring-tones, dial-tones, busy-tones or
“unobtainable” tones or “re-order” tones or “survivability” tones for your system. This screen allows the user to
specify tone-pair attributes that are not found in any of the standard national/regional telephony toning
schemes. To access this customization feature, click on the Custom button on the Regional Parameters screen.
The “Custom” button is active only when “Custom” is selected in the Country/Region field.
