Hi Everyone
Anybody can clarify the reason for Cause value 89 (Reserved for National use) in CLEAR-REQUEST msg. It is given by BSC towards MSS for an MO call attempt.. ITUT says
“Reserved for national use” indicates
codepoints that may be used by operators without the need for international standardization.
I could not understand.
