[0x3/0x83]

No route to destination/ Calling party dropped while on hold (5ESS: 5 Electronic Switching System)/ Bearer service not implemented (1TR6: AT&T ISDN Protocol)

Cause

The ISDN service provider cannot route the call to the indicated destination. Communication Manager does not originate Cause value 03.

Proposed Solution

Procedure

  1. Check if any prefix or service value is missing from the cause value numbers.
  2. Check the Cause Value Information Element (LOC). See Location codes.
  3. Check Communication Manager administration.
    1. Dial-plan/Location: The administration of an incorrect home NPA causes an incorrect code conversion.
    2. IXC: The administration of an incorrect IXC matching pattern or a dial plan without an IXC matching pattern causes incorrect IXC manipulation.
    3. AAR/ARS digit conversion: An incorrect digit string is substituted. The call is routed to the wrong network and over the wrong route pattern. Further conversion is needed, but the dial string is restricted from further conversion.
    4. AAR/ARS digit analysis: Call type is incorrect for the call made with an incorrect number type or number plan information or both, or the call type prevents code conversion. Call routes to an incorrect route pattern with incorrect digit manipulation or code conversion or both.
    5. ARS toll analysis: An incorrect toll or no-toll classification causes incorrect code conversion at the route pattern.
    6. Route pattern: Incorrect entries in the NPA, prefix mark, and toll list/prefix mark fields cause incorrect code conversion. Incorrect number of digits are deleted or incorrect digits are added. IXC or international code digits and user-dialed IXC code fail to parse or IXC routes the call to the wrong interexchange carrier. Number format changed to a format incorrect for the call type. An incorrect service or feature is specified for the call made on a CBC trunk group preference.
