Document Purpose and Target Audience
This document will serve as a reference guide to configure the Avaya BCM 50 IP PBX to interoperate
with Time Warner Cable (TWC) SIP Trunk Service.
This guide is not intended to be a replacement of the PBX manufacture’s user or configuration guide.
It is intended to provide additional guidance on configuring the PBX in preparation to receive voice
service from the SIP Trunk. It provides detailed instructions and best practices for a successful
installation with TWC SIP Trunks.
There are many options for establishing and maintaining service using the Avaya BCM 50 series. This
guide focuses on the minimum configurations essential for successful interoperability with Time Warner
Cable Business Class SIP Trunks.
This configuration guide is based on:
Customer Premise Equipment:
Avaya BCM 50
Business Element Mgr v.62.0.3
TWC Network Equipment:
InnoMedia ESBC 9378-4B
SIP Trunk Components
The Time Warner Cable Business Class (TWCBC) SIP Trunks product is an IP-based, voice only trunk that
uses Session Initiation Protocol (SIP) to connect an IP PBX to the PSTN. The IP PBX uses SIP to exchange
signaling information with the service provider and to deliver and receive voice in IP packets.
The IP PBX is connected to the TWC Enterprise SIP Gateway (ESG), which provides network access for
voice traffic. The customer is responsible for the LAN infrastructure and configuration, including the
physical connection to the LAN port 2 on the ESG.
The ESG is the demarcation point to the TWC network. The ESG is connected to a dedicated router for
SIP Trunks delivered over a fiber connection or to a cable modem when delivered over a DOCSIS
SIP Trunk components located on the customer premise, including connections to the TWC network, are
illustrated below.

All TWC SIP Trunk calls are routed over Time Warner Cable’s IP network and are not routed over the
public internet.
Getting Started
You will need to have the TWC “SIP Trunk Questionnaire” and “Business Class (BC) SIP Trunks:
Customer Cut Sheet” in order to configure your IP PBX for TWC Business Class SIP Trunk service.
Confirm that your IP PBX model number and software versions recorded on the Customer Cut Sheet
match those associated with your current equipment. If they do not, be sure to alert your TWC sales
engineer or TWC project manager as this can impact how TWC designs your service configuration.
Example from Customer Cut Sheet for Cisco UC 560:
While configuring your IP PBX for BC SIP Trunk service, you will need to know your Lead Telephone
Number and the IP address of your IP PBX.
The Lead Number is confirmed on the Customer Cut Sheet as seen below:
The IP Address of the IP PBX was recorded on the SIP Trunk Questionnaire, Section 5. Signaling and
Media as shown below:
This document is intended as an aid to help configure a customer’s IP PBX for interoperability with
TWCBC SIP Trunk Service.
BCM Configurations
The instructions provided in this section are intended to configure the Avaya BCM50 to connect to the
TWC ESG. They are not intended for advanced functionality setups. It is further assumed that there is a
working knowledge of BCM Operations.
Once logged into the BCM50 GUI as an Administrator, follow these steps to configure SIP Trunk Service.
BCM50 Version
Check version and patches – the following version and patches are using during IOT
Figure 1 Avaya BCM50 Version Information
BCM50 Settings
Click “General Settings” tab under Configuration  System  IP Subsystem

Provision SIP Trunk
A SIP Trunk is created on BCM50 to use pilot number registering to the ESG. In our LAB example,
the trunk description is “ESBC” and the Proxy IP address is
Click “Global Settings” tab under Configuration  Resources  IP Trunks  SIP Trunking

Configure SIP Trunk Accounts and Authentication Credential
For challenges received on SIP trunks (from the ESG), i.e., when BCM50 acts as user agent, you configure
a SIP realm, which includes the realm (SIP Domain), username (device or application user), and digest
credentials. To add or update a SIP Realm, perform the following procedure:
Figure 7 Configuration SIP Accounts and Credentials-1

Setup Routes
Selected “BlocA” under Configuration  Telephony  Dialing Plan  “Line Pools”
“DNs” tab. Add DNs to BlocA
Figure 9 Setup Routes
Define the DN length to 4 digits under ConfigurationTelephonyDialing Plan  General.
Figure 10 Setup Dial Plan-1
Define the Public Received number length to “4” digits and Public network dialing plan to
“National” under Configuration  Telephony  Dialing Plan  Public Network
Figure 11 Dial Plan-2
Define the Private Received number length to “4” digits Under Configuration  Telephony
 Dialing Plan  Private Network

Media Parameters
Select module type “IP Trunks”, click on the “SIP Media Parameters” tab under
Configuration  Resources  Telephony Resources, select CODECs for provided voice
service as well as packet time.
Figure 13 Configuring Media Parameters
Select module type “URI Map” tab, clear “e.164/National” field under Configuration 
Resources  Telephony  Resources  SIP Trunking and “Private” tab, select CODECs for
provided voice service as well as packet time.

Select Configuration  Telephony  Dialing Plan  Routing  “Routes” tab, add route
“001”. Edit route “001” column “Use Pool” entry to “BlocA.” and the “DN type” column to
Select the “Destination Codes” tab to assign a destination code for the IP trunks Under
Configuration  Telephony  Dialing Plan  Routing. Configure a destination code “9” to
access outside (IP off-net) calls.

Configure Outgoing Calls from BCM50
Associate a private DN number with a DID number under Configuration  Telephony 
Sets  All DNs. Enter in the “Private OLI” field with a DN and in the “Public OLI” field with
a DID. This enables “calling number translation” (outgoing) for this particular DN number as
illustrated in the figure below.
Figure 17 Configuring Outgoing Calls: calling number translation
BCM Monitor
Use Line Monitor from the provided BCM Monitor Utility monitor incoming or outgoing calls.

Configure Incoming Calls from the ESG
Line Assignment and Access
 Click “Line Assignment” tab under Configuration  Telephony  Sets  All DNs to
configure the “called number translation” (incoming) for a DN number Add line of a DN in
“Line Assignment”. Enter the DN selected in “Line Access” in the “Priv. Received #” field,
and the last four digits of the DID (Public number) in the “Pub. Received #”. Incoming DID
calls will be routed to telephones, based on the trailing portion of the digits received by the
network. The BCM50 will route the call using the last four digits, e.g. 3478.

Target Lines
 Click “Assigned DNs” tab and assign a DN to the selected “Line” number of the DN desired
to program under Configuration Telephony Lines  Target Lines. To display the DID
number on the IP phone LCD screen, enter DID number in the “Name” field “Target Lines”.
Figure 20 Line Assignment and Access-2
Line Pool
 Click “Line Pool Access” tab under Configuration  Telephony  Active Sets and “Line
Access” tab on the top and. Then add “BlocA” as configured in route previously. All
telephone sets need to be configured with the designated “Line Pool” code in order to
access the VoIP.

TWC Turn-up Testing Procedure
To ensure proper service between the IP PBX and the TWC network, test calls from the IP PBX will be
made. Typically, the following call types will be used (call testing varies depending on service
Outbound/Inbound call to a local number
Outbound/Inbound call to a long distance number
Calls to 411 and 611
Outbound calls to a blocked number to verify call blocking settings
Other calls based on customer request , e.g. FAX testing using T.38 or calls to an auto-attendant
to verify DTMF
If you have questions, please contact your Time Warner Cable Business Class Account Executive.
