AT&T IP Flexible Reach Service
Nortel BCM50 Release 3.0 SIP Configuration Guide
1 Introduction
This document provides a configuration guide to assist Nortel Networks BCM50
administrators in connecting to AT&T IP Flexible Reach service via SIP trunks.
This document does not describe procedures to configure the BCM50
for advanced functionality. For more information and procedures,
please refer to the Nortel technical documentation found on the Nortel
website.
1.1 Pre-IP PBX Configuration Activity
This guide assumes that the administrator is knowledgeable in IP PBX
programming and operations.
An important tool that the administrators should have at their disposal prior to
testing their IP PBX with IP Flexible Reach is a network protocol analyzer. Such
software can be used to run traces on problem calls so the information can be
shared with equipment and network engineers. There is a free version of such
software that can be obtained at http://www.wireshark.org/.
A second alternative that customers may use is TCPDUMP which can be found
on most UNIX and Linux systems. To use this software the customer should have
Wireshark or TCPDUMP loaded on a server that is connected to a LAN switch or
hub that can monitor both the signaling and media packets on any calls between
the customer PBX and the IP Flexible Reach managed router. Please note,
however, that AT&T does not offer, warrant, or support this software, and any
use of the Wireshark or TCPDUMP software is entirely at the customer’s own risk.
1.2 Customer Questions
Section 4 of this guid e provides screen shots and instructions for the
configuration of your IP PBX. Should you have questions regarding these
instructions, please contact Brian Stegemoller at +1 (972) 685-6629. When
calling this number please have the f ollowing information available:

1.3 Trouble Reporting
Nortel and AT&T will make every effort to quickly resolve reported troubles. The
time required for trouble shooting can be reduced if the customer has the
necessary detailed information available when reporting a problem. Prior to
reporting a problem please provide a Wireshark or TCPDUMP trace of the failed
call.

IP PBX administrators who would like to provide feedback on the contents of this
document should send it to Brian Stegemoller (brian.stegemoller@nortel.com)

The Nortel BCM50 customer premises site shall consist of the following
components.
• Nortel IP 200x, 11xx, 12xx phones* – These phones use the Nortel
proprietary UNIStim signaling protocol to communicate to the Nortel
BCM50 IP PBX for call feature and routing support. These phones can be
connected to a Nortel Ethernet switch (ES 470, ERS 5520, etc.) t hat
supplies in-line power (IEEE 802.3af) to the phones.
• The following interfaces are provided on all three variants of the BCM50
main module:

Two of these ports also support con nection of optional expansion
units.
o 1 10/100 Ethernet port reserved for direct access management of
the system
o Integrated CallPilot voice mail system
o T1 voice card for connection to the local PSTN.
* RFC2833 DTMF is currently not supported on the IP Softphone 2050; thus the
IP Softphone 2050 is not supported for AT&T IP Flexible Reach service. This will
be fixed in the next major release of the IP Softphone 2050 (release 3).
The following routing scenarios are supported by the Nortel BCM50 IP PBX and
DO NOT use the AT&T Call Control.
• Local Nortel BCM50 phone to other local Nortel BCM50 phone
The following routing scenarios are supported by the Nortel Networks BCM50 IP
PBX and DO use the AT&T Call Control. For voice calls, the G.729 codec shall be
used.
• Nortel BCM50 phones to PSTN (domestic US and international).
• Nortel BCM50 phones to legacy PBX site with Cisco gateway.
• Legacy PBX site with Cisco gateway to Nortel BCM50 phones.
• Nortel BCM50 phones at one Nortel BCM50 IP PBX site to Nortel BCM50
phones at another Nortel BCM50 IP PBX site
If the customer has subscribed to Calling Plans B and C (Local), then the
following routing scenarios are supported by the BCM50 IP PBX and DO use the
AT&T Call Control. For voice calls, the G.729 or G.711 codec may be used.
BCM50 selects G.729 as the highest priority codec.
• Inbound PSTN to BCM50 phone
• Outbound local PSTN calls from the BCM50 phones
• Outbound local N11 (i.e. 411, 911) calls from the BCM50 phones
