Version 2.1, 08.01.2007
0x421 Incorrect ending
0x423 The requested service is not supported by the VoIP provider.
0x480 The dialled number is temporarily unavailable.
0x481 The recipient is not available.
0x482 Double service query
0x483 Too many "hops":
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 was previously
specified by the original sender of the query.
0x484 Wrong number:
In most cases this response means that you have simply omitted one or more digits in the
phone number.
0x485 The URI dialled is not unique and cannot be processed by the VoIP provider.
0x486 The called party is busy.
0x487 General faults:
The call was interrupted before a call was established. The status code confirms receipt of
the interruption signal.
0x488 The server cannot process the query because the data entered in the media description is
not compatible.
0x491 The server notifies that the query will be processed as soon as a previous query has been
completed.
0x493 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.
0x500 The proxy or the receiving device has discovered a fault while executing the query, which
makes further execution of the query impossible. In this case, the caller or the phone dis-
plays 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.
0x501 The query cannot be processed by the recipient because the recipient does not have the
functionality 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 permit-
ted in the current context, a 405 is sent instead of 501.
0x502 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.
0x503 The query cannot currently be processed by the receiving device or the proxy because the
server is either overloaded or is being serviced. If it is possible for the query to be repeated
in the foreseeable future, the server informs the caller or the phone of this.
0x504 Time limit at the gateway
0x505 The server rejects the query because the indicated version number of the SIP protocol does
not at least concur with the version that is used by server or the SIP device involved in this
query.
0x515 The server rejects the query because the message exceeds the maximum permitted size.
0x600 The called party is busy.
