Error
Code
Description/Recommendation
3843 Cause Value 3. No route to destination. Request received to route call through a
transit network that is recognized but not allowed to carry the call or not able to
serve the destination. The service provider cannot route the call to the indicated
destination. Communication Manager does not originate Cause Value 3.
The repair steps are based on Tier 4 recommendations:
1. Check the numbers sent for any missing prefixes or service values that were
needed to access the network.
2. Check the Cause Information Element Location Code.
3. Check Communication Manager administration:
a. Dial plan/Location: The home NPA is administered incorrectly, causing
incorrect code conversion.
b. IXC: The IXC matching pattern is administered incorrectly or not at all on
the dial plan, causing incorrect IXC manipulation.
c. AAR/ARS digit conversion: The wrong digit string substitution is being
made. The call is being routed into the wrong network and over the wrong
route pattern. Further conversion is needed but the dial string is restricted
from further conversion.
d. AAR/ARS digit analysis: Call type is incorrect for the call being made
specifying the wrong type of number and/or number plan information, or it
is preventing code conversion from taking place. Call is being routed to
the incorrect route pattern where the incorrect digit manipulation and/or
code conversion is taking place.
e. ARS toll analysis: Toll/no toll classification is incorrect, causing incorrect
code conversion at the route pattern.
f. Route pattern: Incorrect code conversion due to wrong entries in NPA,
prefix mark, and toll list/prefix mark fields. Deleting the wrong number of
digits or inserting the wrong digits. Failing to strip IXC or international code
digits, stripping a user-dialed IXC code, or IXC forcing the call to the
wrong inter-exchange carrier. Number format changed to a format
incorrect for the call type. The incorrect service or feature is specified for
the call being made on a CBC trunk group preference.
