No circuit or 

channel 

available

A resource on the switch is unavailable for a call.  For BRI 

endpoints: This cause value is not logged.  For ASAI or Avaya 

Adjuncts: This condition means that there are no available trunks for 

an outgoing call request.

1. Verify that the adjunct is administered to support the trunk 

capabilities of the switch.

2. Investigate trunk group status by issuing status trunk 

commands from the SAT or by requesting a trunk group query 

or queries from the adjunct.

3. Perform trunk diagnostic procedures outlined in this manual.
4. If step 3 does not resolve the problem, escalate to the next tier.

Switch takes control to limit received traffic.  For BRI endpoints: This 

cause value is not logged.  For ASAI or Avaya Adjuncts:

1. Refer to the CallVisor protocol reference manual.
2. If step 1 does not resolve the problem, escalate to the next tier.

Requested 

Facility Not 

Subscribed

Requested facility is implemented, but not administered.  Potential 

administration problem with endpoint or adjunct.  For BRI endpoints:

1. Verify the switch administration of endpoint using display 

station or display data-module.

2. If step 1 does not resolve the problem, refer to the endpoint’s 

service manual and verify administration on the endpoint.

3. If step 2 does not resolve the problem, escalate to the next tier.

For ASAI adjuncts:

1. Display the Customer Optional Features screen (administration 

screen) on the switch to determine which ASAI capabilities are 

turned on in the switch.

2. Verify that the adjunct is administered to support the identical 

capabilities as the switch.  If there is a mismatch in the 

administered capabilities, then re-administer the switch and/or 

the adjunct to establish a consistent set of desired capabilities 

on both the switch and the adjunct.

3. If step 2 does not resolve the problem, escalate to the next tier.

For Avaya adjuncts:

1. Display the Customer Optional Features screen (administration 

screen) on the switch to determine whether the Avaya adjunct 

is set enabled on in the switch.

2. If error type 2567 or 2568, verify the Avaya adjunct version, 

and re-administer if needed.

3. If step 2 does not fix the problem, escalate to the next tier of 

support
