21 Call was rejected. Although the equipment sending this cause
code is neither busy nor incompatible, the equipment sending
this cause code does not want to accept the call. The cause
can be generated by the network to indicate that the call
might have been cleared as a result of a supplementary ser-
vice constraint. No ITU-T Q.850
22 Number was changed. The number of the called party is no
longer assigned. A new number must be used to call the
called party. No ITU-T Q.850
23 User rejects all calls with calling line identification restriction
(CLIR). The called party returns this cause code when the call
comes in without calling party number information and the
called party requires this information. No ATM Forum UNI

27 Destination is out of order. The user cannot reach the destina-
tion because the interface to the destination is not function-
ing properly; that is, a signaling message could not be deliv-
ered to the destination. Yes ITU-T Q.850
28 Number format is not valid (address incomplete). The called
party is unreachable because the number of the called party is
not in the proper format or it is not complete. No ITU-T Q.850

assigned to the SPVC. Yes ITU-T Q.2610
37 User cell rate is unavailable. The requested cell rate is
unavailable for the SPVC. Yes ITU-T Q.2610

agreement). The problem will probably last a long period of
time; that is, an immediate retry of the call is not likely to suc-
ceed. Yes ITU-T Q.850
41 Temporary failure. The problem will probably last a short
period of time; that is, an immediately retry of the call has a
good chance to succeed. Yes ITU-T Q.850
