Call Termination Cause Codes

Revised: August 10, 2011, OL-24995-01

Introduction

This appendix lists call termination cause values and definitions.

BTS 10200 Call Termination Cause Values and Definitions

Table A-1 lists the BTS 10200 call termination cause values and definitions.

Note A "*" next to the value in Table A-1 indicates the cause code is not a standard BAF cause code; it is unique to the Cisco BTS 10200 Softswitch. All values of 400 or higher are used internally only and do not appear in the billing records transmitted from the EMS.

BTS 10200 Bye Message Cause Code to GR-1100 Cause Code Mapping

The call termination cause code contained in a CDR is a mapping of the BTS 10200 call termination code to a GR-1100 code. In several cases, the cause code used during call processing does not map directly into a GR-1100. In these instances, the mapping shown in Table A-2is performed to generate the CDR call termination cause code:
