Cause
This cause value has end-to-end significance. Communication Manager returns this cause value to the user who has originated the call.
Cause value 58 indicates that the call cannot be completed because the user has requested a bearer capability in the SETUP message which is implemented by the equipment generating this Cause Value. However, there are no resources available currently to complete the call.
CAUSE
Cause value 58 (1TR6) indicates that the remote device, endpoint, or PBX does not respond with an ALERTING/PROGRESS/CONNECT indication within the prescribed time period allocated by the expiry of the T303 or T310 timers in the Q.931 specification.
Proposed Solution 2
Procedure
- Check the diagnostic information (DIAG) for the bearer capability attributes that are not available. See Event data 2.
- Check Communication Manager administration for cause value generated by the network.
- Route pattern: An incorrect ITC or BCIE or both. These fields affect how the bearer capability is encoded in the SETUP message.
- The ITC administered on the originating endpoint is incorrect for this call, or the speed options for calls over these ISDN facilities in the device itself are incorrect or both.
- Incorrect data speed option set in the BRI device causes a call from a BRI endpoint sequencing through Communication Manager to create a SETUP message with the wrong bearer capability.
- A call sequencing through Communication Manager ISDN trunk group to ISDN trunk group has a bearer capability that is not supported by the outgoing ISDN facilities or network.
- A call sequencing through Communication Manager on a non-ISDN trunk group transferring to an ISDN trunk group has an incorrect bearer capability assigned to the incoming trunk group. The BC and ITC fields on the incoming trunk group are administered incorrectly.
