Configuring Regional Parameters and Supplementary Services Distinctive Call Waiting Tone 7 Example 2: Distinctive Ring (short, short, short, long) 60(.2/.2,.2/.2,.2/.2,1/4) where: • Number of Cadence Sections = 1 • Cadence Section 1: Section Length = 60s • Number of Segments = 4 • Segment 1: On=0.2s, Off=0.2s • Segment 2: On=0.2s, Off=0.2s • Segment 3: On=0.2s, Off=0.2s • Segment 4: On=1.0s, Off=4.0s • Total Ring Length=60s Distinctive Call Waiting Tone When the phone is off-hook on a call, the call waiting tone plays. Support for Distinctive Ring is based on the Alert-Info header that supports the Distinctive Call Waiting tone. The distinctive call waiting tone is generated based on the phone call waiting tone frequency and gain values, and the cadence value of the matched ring tone. The cadence value (following the c= element) of the matched ring tone must be an integer from 1 to 9 that specifies the ring cadence under the Regional tab of the phone web user interface. If there is no matching ring tone name, or an invalid cadence value is specified, the configured Call Waiting Tone is used.
