AT&T IP Flexible Reach and AT&T IP Flexible Reach with AT&T Business in a Box
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 and AT&T IP Flexible
Reach with AT&T Business in a Box
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 AT&T IP Flexible Reach and AT&T IP Flexible Reach
with AT&T Business in a Box is the Wireshark network protocol analyzer. This
software can be used to run traces on problem calls so the information can be
shared with equipment and network engineers. This free software can be
obtained at
The customer may also use TCPDUMP which can be found on most UNIX and
Linux systems. 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.
1.2 Customer Questions
Section 4 of this guide 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 ((972) 7455139 after 2/22/2010). When calling this number please have the following
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.

2 Special Notes
Emergency 911/E911 Services Limitations and Restrictions
Although AT&T provides 911/E911 calling capabilities, AT&T does not warrant or
represent that the equipment and software (e.g., IP PBX) reviewed in this
customer configuration guide will properly operate with AT&T IP Flexible Reach
to complete 911/E911 calls; therefore, it is Customer’s responsibility to ensure
proper operation with its equipment/software vendor.
While AT&T IP Flexible Reach services support E911/911 calling capabilities
under certain Calling Plans, there are circumstances when that E911/911 service
may not be available, as stated in the Service Guide for AT&T IP Flexible Reach
found at http://new.serviceguide.att.com. Such circumstances include, but are
not limited to, relocation of the end user’s CPE, use of a non-native or virtual
telephone number, failure in the broadband connection, loss of electrical power,
and delays that may occur in updating the Customer’s location in the automatic
location information database. Please review the AT&T IP Flexible Reach Service
Guide in detail to understand the limitations and restrictions.
BCM Soft Phones not currently supported
Nortel BCM soft phones are not currently supported with the AT&T IP Flexible
Reach and AT&T IP Flexible Reach with AT&T Business in a Box Services.
Ring back Issues with Unattended Transfers
An unattended transfer is one in which the party initiating the transfer hangs up
prior to answer by the party to whom the call is being transferred. When 2
phones are in an active call on the BCM50 and one of those phones performs an
unattended transfer to certain endpoints on the AT&T network, the BCM50
phone remaining on the call will not hear ring back prior to answer.
T.38 Fax must be used
Nortel recommends using T.38 as the means to transport fax on the BCM50.
No NAT Device between BCM50 and BIB Managed Router
Due to a limitation in the AT&T Managed Business In a Box (BIB) Router
software, the network configuration at Customer Premise CANNOT contain any
NAT device between BIB Router and BCM50 IP-PBX system. A network
configuration with a NAT device between BIB Router and BCM50 results into no
voice path for any direction calls.

Figure 1: AT&T BVoIP Network
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.) that
supplies in-line power (IEEE 802.3af) to the phones.

• The following interfaces are provided on all three variants of the BCM50
main module:
o 12 digital station ports supporting digital phones.
o 4 Analog Loop Supervised Trunks (NA networking standards).
o 4 Analog Station interfaces with message waiting and CLID
support.
o 3 port 10/100 Ethernet switch with auto sensing and auto polarity.
Two of these ports also support connection of optional expansion
units.
o 1 10/100 Ethernet port reserved for direct access management of
the system
o Integrated CallPilot voice mail system
* 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 and AT&T IP
Flexible Reach with AT&T Business in a Box services. 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
