Returns the system ciphering-algorithm priority to the default of GEA0 - which means that no ciphering will
be done.

ciphering algorithm configurations.
reject
: Instructs the SGSN to reject a call when the ciphering algorithms do not match.
failure-code cause_code
: Instructs the SGSN to include a GMM cause code in the Reject
message. Enter an integer from 2 to 111; default code is 14 (GPRS services not allowed in this
PLMN). Refer to the GMM failure cause codes listed below (information has been taken from
section 10.5.5.14 of the 3GPP TS 124.008 v7.2.0 R7):
