Transferred E&M Trunk Calls & SMDR

Technical Service Bulletin
SX-2000®

This Technical Service Bulletin is intended for Customer Service and Installation Personnel involved in the service of the MITEL® SX-2000. This bulletin is intended to identify SMDR conditions that apply when calls are transferred through E&M Trunks (Analog or Digital).

OVERVIEW

This document identifies SMDR conditions that apply when calls are transferred through E&M trunks (Analog or Digital). This is the typical interface for some Voice Mail (Mitel Mail) and IVR applications using Auto Attendant functionality. These SMDR conditions directly affect Cost Accounting and ACD Reports (TASKE). Other interfaces to the SX2000 will have to be implemented to provide accurate SMDR reporting.

GENERAL

Calls can be transferred by an Auto attendant application which is interfaced through E&M trunks to the Mitel SX2000 PABX. This application is effective for call processing but results in inconsistent and incomplete SMDR records which will impact the accuracy of Cost Accounting and ACD Reports.

ADDITIONAL

SMDR is inconsistent and incomplete when transferred from an E&M Trunk (Analog or Digital).

Examples of these SMDR records are shown :

Test A : DID call to E&M Trunk which is transferred (Unsupervised) to an ACD Path

10/26 02:12P 00:00:11 X011 001 P2901 001 2801
10/26 02:12P X011 2901 X025
10/26 02:12P 00:00:18 X011 009 94 X025X P001

Test B : DID call to E&M Trunk which is transferred (Supervised) to an ACD Path

10/26 02:19P 00:00:03 X011 000 2901 2801
10/26 02:19P 00:00:19 X011 2901 X025
10/26 02:19P 00:00:16 X011 005 94 X025T 2801

Test C : Internal Call to E&M Voice Mail which is transferred to an ACD Path

10/26 02:24 P 2303 X025

Note: 1. Similar SMDR records are ouput when calls are originated from other trunk types such as

MSDN, T1D4, LS/GS, etc..

2. RLT (Release Link Trunks) are also impacted by erroneous SMDR records.

SOLUTION

ONS, COV or DNIC ports interface to the some Voice Mail and IVR's. These type of interfaces must be installed specifically for Auto Attendant functionality. This will provide accurate SMDR records required for Cost Accounting and ACD Reporting. Although, this may result in a lack of VM integration (i.e. Enhanced Inband Signaling) such as providing the originating party information from an incoming trunk (ANI).
