<interval> A decimal number (0–255) specifying the silence interval time in units of
0.10 seconds between the end of one ring interval and the start of the
next ring interval. A value of 0 forces the modem to report the OK result
code and immediately after the first ringback. The range is 0.1 to 25.5
seconds for <interval>=1 to 255.

Ringback Timer
Sets the length of time that the modem will wait for ringback. If the modem does not
detect a ringback within the time period <interval>, the modem assumes that the
remote device has going off-hook and returns the OK result code. The modem only
uses this command in call origination transactions. A +VRN setting greater than the
S-Register S7 setting means that only the S7 timer is in effect.
AT+VRN=<interval>
<interval> A decimal number specifying the time period in units of 1.0 seconds that
the modem will wait for ringback during a call origination. A value of 0
forces the modem to report the OK result code immediately after dialing.
The range is 1 to 25 seconds for <interval>=1 to 25.
0–10 (in 1.0 second increments)
10 (10 seconds)
OK if <interval> = 0-25.
ERROR if the <interval> parameter entered is out of range or the modem is not in
voice mode.
+VRN? Displays current or selected values.
+VLN=? Displays a list of the supported values.
