1163 - GWS rcvd invalid GTI in TT screening

This message indicates that a message that was not a SCCP message or an SCCP message that does not contain a TT passed the Allowed TT screening. Allowed TT screening makes sense only for SCCP messages that contain TT. When a non-SCCP message or a SCCP message that does not contain a TT is screened for Allowed TT, it is forced to pass screening and this message is generated.
