+VDR=<enable>,<report>—Distinctive Ringing and Cadence Report
Use this command to enable or disable the distinctive ringing feature. Distinctive ringing features are
identified by the DROF=<length of ring in 0.1 s increments> and DRON=<length of silence in 0.1 s
increments> result codes. The default value assigned to the <enable> and <report> parameters is zero.
Result codes:
• OK in <enable> = 0, 1 and <report> = 0—255.
ERROR if <enable> ≠ 0, 1 and <report> ≠ 0—255.
