* These errors are not defined by the ETSI (EuroISDN) specification, but may occur in other ISDN implementations.  

00 - Normal Disconnect

The call has been disconnected in the normal way; for example by hanging up a phone or terminating a data connection.

01 - Unassigned (Unallocated number)

The number you dialled is incorrect.

Check the number and any prefixes you need to access the network if you are connected to a PBX. For more information on which part of the ISDN network is reporting the error, refer to the location code.
02 - No route to specified transit network

Your ISDN service provider’s equipment cannot route the call through the specified network, either because this network does not exist or because it is not compatible with your ISDN service provider’s equipment.

Check the number and any prefixes you need to access the network if you are connected to a PBX.
Check that the type of call you are making (data, voice, fax) can be routed between the ISDN networks serving both you and the destination.  
Check that the Bearer Capabilities of the call are acceptable to the ISDN networks serving both you and the destination.  

For more information on which part of the ISDN network is reporting the error, refer to the location code.

03 - No route to destination

Your ISDN service provider cannot route the call to the specified destination.

Check the number and any prefixes you need to access the network if you are connected to a PBX.
Check that the type of call you are making (data, voice, fax) can be routed between the ISDN networks serving both you and the destination.  
Check that the Bearer Capabilities of the call are acceptable to the ISDN networks serving both you and the destination.
For more information on which part of the ISDN network is reporting the error, refer to the location code.
04 - Send special information tone

The remote number you dialed could not be reached.

Check the number and any prefixes you need to access the network if you are connected to a PBX.
Contact your ISDN service provider.
Contact the person responsible for the service (for example, your Internet service provider).
05 - Misdialled trunk prefix

The remote number you dialed could not be reached.

Check the number and any prefixes you need to access the network if you are connected to a PBX.
If you are using a PBX check the configuration of the PBX.
Contact your ISDN service provider.
Contact the person responsible for the service (for example, your Internet service provider).

06 - Channel unacceptable

The call attempt failed because the channel cannot be used.

If you are using a PBX check the configuration of the PBX.
Contact your ISDN service provider.
If you are using a Primary Rate ISDN connection (24 or 30 B-channels) check with your ISDN service provider exactly how many channels are provisioned.

07 - Call awarded and being delivered in an established channel

An incoming call is being established.

If you are using a PBX check the configuration of the PBX.
Contact your ISDN service provider if this condition persists.
08 - Preemption

Your call attempt was blocked. This can happen, for example, if another call has a higher priority than your call.
Wait and try the call again later.
If you are using a PBX (or the remote site that you are connecting to uses a PBX) check the configuration of the PBX.
If the condition persists, contact your ISDN service provider.
09 - Preemption, circuit reserved for re-use

Your call attempt was blocked. This can happen, for example, if another call has a higher priority than your call.
Wait and try the call again later.
If you are using a PBX (or the remote site that you are connecting to uses a PBX) check the configuration of the PBX.
If the condition persists, contact your ISDN service provider.
10 - Normal call clearing

The remote device terminated the connection.
This might or might not indicate an error.
For example, if you requested a callback, then the remote device will disconnect and then call you back; this indicates normal behavior.
The remote device may have disconnected you because your session has been inactive for a some pre-determined time.
If the remote device terminated the connection unexpectedly, contact the person responsible for the service (for example, your Internet service provider) to determine if there is a problem with the remote device. If the device is malfunctioning, ask if you can dial into an alternative device to use the service.
11 - User busy

The device you called is busy.

Check the number you are calling.
Wait and try again later.
If the condition persists, contact your ISDN service provider.
12 - No remote response

The remote device you called did not respond.

This usually indicates a problem with the remote device or application.
Check the number you are calling.
If the remote site that you are connecting to uses a PBX, check the configuration of the PBX.
If the condition persists, contact the person responsible for the service (for example, your Internet service provider).
13 - No answer

The remote device did not answer your call.

The remote device or application is probably working properly, it just did not answer your call.

If the condition persists, contact the person responsible for the service (for example, your Internet service provider).
14 - Subscriber absent

The mobile remote device you called is not available (the device has disconnected from the ISDN network).

Contact the person responsible for the service or device.
15 - Call rejected

The remote device rejected your call.

If you configured D-channel callback, this does not indicate an error; the remote device will call you back.
If you did not configure callback, then there might be a problem concerning the service you need to use.
If the remote site that you are connecting to uses a PBX, check the configuration of the PBX.
If the condition persists, contact the person responsible for the service (for example, your Internet service provider).
16 - Number changed

The ISDN number you dialed is no longer assigned to the remote party you want to call.

Check the number you are calling.
If the remote site that you are connecting to uses a PBX, check the configuration of the PBX.
Contact the person responsible for the service (for example, your Internet service provider) to obtain the new ISDN number.

Your call is being routed to a different ISDN number.

Check the number you are calling.
If the remote site that you are connecting to uses a PBX, check the configuration of the PBX.
Contact your ISDN service provider to determine if you should reconfigure the remote ISDN number.
19 - Exchange routing error

Your call cannot be successfully routed to the remote party.

Check the number you are calling.
If you are using a PBX (or the remote site that you are connecting to uses a PBX) check the configuration of the PBX.

The number you called is incorrect.

Check the number you called.
If you are using a PBX (or the remote site that you are connecting to uses a PBX) check the configuration of the PBX.

1D - Facility rejected

Your call was not completed because the ISDN network does not support a service you have tried to use.

If you are using a PBX, check that it supports the type of call that you are making. You may need to check the Bearer Capabilities of the call.

1E - Response to STATUS ENQUIRY

The ISDN network forwarded a STATUS ENQUIRY message.

If this condition persists, contact your ISDN service provider.
1F - Normal unspecified

This message indicates that a normal event occurred.

For example, if you requested a callback, then the remote device will disconnect and then call you back; this indicates a normal event.
If the remote device terminated the connection unexpectedly, contact the person responsible for the device or service.
22 - No circuit/channel available

The call cannot be completed because there are no available channels.

If another application is using your B-channels, close it to free your B-channels.
