480
The dialled number is temporarily unavailable.
481

482
Double service query
483
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 maximum number is defined before-
hand by the original sender of the query.
484
Wrong number:
In most cases this response means that you have simply omitted one or more digits in the
phone number.
485
The URI dialled is not unique and cannot be processed by the VoIP provider.
486
The called party is busy.
487
General faults:
The call was cancelled before a call was established. The status code confirms receipt of the
interruption signal.
488
The server cannot process the query because the data entered in the media description is not
compatible.
491
The server notifies that the query will be processed as soon as a previous query has been
completed.
493
The server rejects the query because the phone cannot decrypt the message. The sender has
used an encryption method that neither the server nor the receiver phone can decrypt.
500
The proxy or the receiving device has discovered a fault while executing the query. It is there-
fore impossible to execute the query. If this occurs, the caller or the phone displays the fault
and repeats the query after a few seconds. The number of seconds after which the query can
be repeated may be transmitted to the caller or phone by the receiving device.
501
The query cannot be processed by the recipient because the recipient does not have the func-
tionality that the caller requires. If the recipient understands the query but does not process
it because the sender does not have the necessary rights or the query is not permitted in the
current context, status code 405 is transmitted instead of 501.
502
In this case, the receiving device that transmits this error code is a proxy or a gateway and
has received an invalid response from its gateway via which this query is to be processed.
