136 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
Troubleshooting
● Check the diagnostic information (DIAG) for the transit network identity of the unreachable
network. See Cause Values and their meanings/interpretations
on page 128.
● Check the numbers sent for any missing prefixes or service values that were needed to
access the network.
● Check that the call type (data, voice, fax) can be routed between the ISDN networks
serving both ends of the call.
● Check that the bearer capabilities of the call are acceptable to the ISDN network serving
both ends of the call.
● Check the Cause Value Information Element (LOC). See Location Codes on page 130.
● Check Communication Manager administration.
- 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.
- Route pattern: Incorrect digits or IXC were inserted. Incorrect number of digits were
deleted. An incorrect ITC and/or BCIE were specified, affecting the SETUP message
bearer capability encoding. An incorrect service or feature was specified for the
preference. The number format specified is wrong for the call type.
- The ITC administered on the originating endpoint might be incorrect for this call.
- Incorrect data speed option is set in the BRI device, causing a call from a BRI endpoint
tandeming through Communication Manager to create a SETUP message with the
wrong bearer capability.
