Description (partial)

MME does not send the complete "SGSN Context Response"
It is supposed to send :
SGSN Context Response with  cause "Request Accepted" (OK) and  "Next Extension Header" of type "Suspend Response" (NOT OK).

Therefore, the SGSN never sends ACK to MME.

The voice call (CS) functions fine and there is no impact!

CSFB to 2G during a voice call - interrupting 4G data.
