Check the numbers sent to see if any prefixes or service values that were needed to 
access the network were not sent.

Check the Cause Value Information Element (LOC). See

Check Communication Manager administration.

- Dial-plan/Location: The home NPA is administered incorrectly, causing incorrect code 

conversion.

- IXC: The IXC matching pattern is administered incorrectly or not at all on the dial-plan, 

causing incorrect IXC manipulation.

- 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.

- 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. 

- ARS toll analysis: Toll/no toll classification is incorrect, causing incorrect code conversion 

at the route pattern.

- 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 interexchange carrier.

- Trunk Group: The incorrect service or feature is specified for the call being made on a 

CBC trunk group preference. The number format is being changed to a format incorrect 
for the call type.

[0x2/0x82] -
No route to specified transit network/
Calling party off hold (5ESS: 5 Electronic Switching System)
The ISDN service provider’s equipment cannot route the call through the specified network. The 
network either does not exist or is not compatible with the ISDN service provider’s equipment.
This Cause Value has local significance only. The ISDN network between the user and the 
equipment generating the Cause Value might:

●

Send no cause indication through the network.

●

Send a more generic Cause Value through the network.

Because this Cause Value has only local significance, on tandem calls Communication 
Manager might map it to 

 instead of passing it back through the network.
