Parameter
4.3.13. AT+QCFG="urc/ri/ring" RI Behavior When RING URC is Presented
AT+QCFG="urc/ri/ring", AT+QCFG="urc/ri/smsincoming" and AT+QCFG="urc/ri/other" control the
RI (ring indicator) behavior when a URC is reported. These configurations will be stored into NV
automatically. The ring indicator is active low. AT+QCFG="urc/ri/ring" specifies the RI behavior when
URC RING is presented to indicate an incoming call.
The sum of parameter <activeduration> and <inactiveduration> determines the interval time of “RING”
indications when a call is coming.
Parameter
<enable> 0 Refused to establish multi PDNs with the same APN profile
1 Allowed to establish multi PDNs with the same APN profile

Response
If <typeri>, <pulseduration>, <activeduration>,
<inactiveduration> and <ringnodisturbing> are omitted,
return the current configuration:
+QCFG:
"urc/ri/ring",<typeri>,<pulseduration>,<activeduration>,
<inactiveduration>,<ringnodisturbing>,<pulsecount>
OK
If all configuration parameters are entered, set the RI
behavior when RING URC is presented:
OK
