Meaning
Temporarily redirected.
The phone is informed that the called party cannot be reached under the
dialed number. The call is redirected for a limited period. The phone is also
notified of the length of the redirection.
The query is sent to a different "proxy server", e.g. to balance incoming que-
ries. The phone will make the same query once again to another proxy server.
This is not a redirection of the address per se.
Other service:
The query or call could not be transferred. However the phone is notified what
other options are available to connect the call.
Wrong call
Not authorized
The requested service is not supported by the VoIP provider.
Wrong phone number.
No connection on this number.
Example: In a local call you have not dialed the area code although your VoIP
provider does not support local calls.
Method not permitted.
Not acceptable.
The requested service cannot be provided.
Proxy authentication required.
The party cannot be reached (e.g. account has been deleted).
The requested service is not available from the VoIP provider.

Incorrect ending
Incorrect ending
The requested service is not supported by the VoIP provider.
The dialed number is temporarily unavailable.

Double service query
Too many "jumps":
The query was rejected because the service server (proxy) has decided that
this query has already passed through too many service servers. The maxi-
mum number is defined beforehand by the original sender of the query.
