Appendix 2 - Call Clearing Cause Codes
ETSI-Based Protocols
This section describes call clearing cause codes for the
following protocols:
• ETSI
• TPH
• VN4
• CorNet-T
• CorNet-N
Cause
Number Cause
1 Unallocated (unassigned) number
The destination requested by the calling user
cannot be reached because, although the number
is in a valid format, it is not currently assigned
(allocated).
2 No route to specified transit network
The equipment sending this cause has received a
request to route the call through a transit
network which it does not recognise, either
because the transit network does not exist or
because it does not serve the equipment sending
this cause.
3 No route to destination
The destination requested by the calling user
cannot be reached because the network through
which the call has been routed does not serve the
desired destination.
6 Channel unacceptable
The called user cannot negotiate for a B-channel
other than that specified in the SETUP message.
