Check calling number plan/type. Must be isdn/national 10 digits.
In teh future, always include the complete call setup trace, not just what you deem is relevant.

We are having the exact same issue. We are having a problem dialing only specific 800 numbers. We are receiving the same error code.

Cause i = 0x83AF - Resource unavailable, unspecified
Progress Ind i = 0x8381 - Call not end-to-end ISDN, may have in-band info

Toll free numbers are unique in their handling requirements. If you have both local telco connections and dedicated LD connections, you will find that you can hand of *SOME* toll free traffic, but not all, on the dedicated LD circuit.
The reason for this is that unless the LD carrer you are attached to is servicing that 800 number, they will have no idea where to send it.
Toll free calls should be routed out via the LOCAL telco connection. The local telco can do a lookup to see who the toll free number is PIC'ed to, and forward it to the appropriate LD carrier for termination.
If you send it to the LD carrier, and they don't terminate that 800 number (i.e. another carrier is servicing it), you'll get the error you are describing.

Also, some toll free numbers are restricted in that they can only be dialed from certain areas. If you hit a restriction like this, you very well might see this error as well.
