240 GPRS commands 6615-2220
+CRC – Cellular result codes
Description:
This command enables a more detailed ring indication, in case of incoming call (voice or
data). Instead of the string “RING”, an extended string is used to indicate which type of
call is ringing (e.g. +CRING: VOICE).
These extended indications are:
+CRING: ASYNC for asynchronous transparent
+CRING: REL ASYNC for asynchronous non-transparent
+CRING: VOICE for normal speech.
+CRING: FAX for fax calls
+CRING: GPRS GPRS network request for PDP context activation
If the MT is unable to announce to the TE the network's request (for example it is in
V.25ter online data state) the MT rejects the request. No corresponding unsolicited
result code is issued when the MT returns to a command state.
Syntax:
See +CRC command descibed in the data commands section
Parameters:
No parameter.
