#VRA - Ringback Goes Away Timer (Originate)

This command can be used, when originating a voice call (#CLS=8) to set the "Ringback Goes Away" timer value, i.e., an amount of time (in units of 100 ms) measured from when the ringback cadence stops once detected. If ringback is not detected within this period, the modem assumes that the remote has picked up the line and switches to Online Voice Command Mode. Every time a ringback cycle is detected, this timer is reset.

Parameters:
n = 0 - 255 (0 - 2.55 seconds)

Default:
70

Result Codes:
OK - If n = 0 - 255

ERROR - Otherwise

Command Options:
#VRA? - Returns the current setting of the #VRA command as an ASCII decimal value in result code format.

#VRA=? - Returns the message: 0 - 255

#VRA=0 - Turns off the ringback goes way timer. After one ringback, the dialing modem sends VCON and enters Online Voice Command Mode immediately.

#VRA=n - Where n defines the period without ringback (after at least one ringback has been detected) in 100 ms units.
