Status Meaning
code
0x420 Incorrect ending
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 is defined beforehand 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 participant is busy.
0x487 General error:
The call was cancelled 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 reports 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. It is therefore
impossible to execute the query. If this occurs, the caller or the phone displays the fault and repeats
the query after a few seconds. If applicable, 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 permitted in the current
context, status code 405 is transmitted 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 be processed by the receiving device or the proxy at present 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.
0x504 Time limit exceeded at the gateway
0x505 The server rejects the query because the indicated version number of the SIP protocol does not
concur with at least the version that is used by the server or SIP device involved in this query.
0x515 The server rejects the query because the message exceeds the maximum permitted size.
0x600 The called participant is busy.
0x603 The called participant has rejected the call.
