When the product receives a call, it sets the Ring Indicator signal and sends the ASCII  
“RING” or "+CRING: " string to the application (+CRING if the cellular result  
code +CRC is enabled).  
AT+WRIM=1,71

Use above AT command to set/activate the Ring indicator.

Note: bit field (0…0)1000111 (0x47 or decimal  
71) to enable IP packets, RING, +CRING,  
+CCWA, +CLIP, +CMT, +CMTI, +CDS,  
+CDSI, +WBCI, +WDCI

Try and reply for the same.
