1. Introduction
This document provides a typical network deployment of Business Communication Manager (BCM) 50
Release 5.0 and BCM450 Rls 5.0 utilizing the PAETEC SIP Trunking service offering. The document
provides the software line up, supported features as well as procedures for configuring a SIP trunk
between the BCM Release 5.0 and PAETEC. This document should serve as general guideline only,
since it is not possible to document every possible variation of configuration. Further information may be
obtained from your Nortel support representative.

3. Features
3.1. Features Supported
The following are capabilities provided by this solution:
• Basic calls (G711a-law 20 ms, G729 20ms)
• Calling line (number) identification presentation (CLIP)
• DTMF (RFC2833)
• Call hold
• Call transfer (Blind and consultative transfers)
• Ad hoc conference calls
• Meet-Me conference calls hosted on the BCM
• Call forward
• Call Redirection to Voice Mail on BCM
• Fax using G711 only
• Inter-office tandem calls
• Find Me Follow Me
• Silent Recording
3.2. Technical Caveats
The following are limitations with this solution:
• Fax over T.38 is not supported by any of PAETEC’s SIP Trunking service
• With PAETEC’s Broadworks SIP Trunking service, authentication of SIP requests from BCM are
not supported by this solution. So when deploying with Broadworks, authentication must be
turned off on the BroadWorks soft switch.
• Deployments where BCM is located behind a NAT device is not supported
• PAETEC’s LGP SIP trunking service sends DTMF digits both inband and using RFC2833 when
G.711 is negotiated between the BCM and the LGP. BCM does not support inband DTMF. As a
work around, on the BCM, configure G.729 as the first preferred codec and G.711 as the second
preferred codec.

4. Network Diagram
Figure 1 shows a typical deployment of a SIP trunk between BCM Release 5.0 and PAETEC. In the
diagram, there is no NAT between the BCM and PAETEC. Therefore the IP address of the BCM and any
BCM IP phone must be routable from PAETEC.

7. Click on the route just created
8. Under the Use Pool column, double click to select BlocA from the drop down list.
9. Under the DN Type column, double click to select Public (Unknown) from the drop down list
10. Click on the Destination Codes tab.
11. Configure a destination code to route dialed digits by clicking on the Add button. Digits that begin
with this destination code will be presented to the SIP trunking component on the BCM for routing
towards the Service Provider.
12. In the Add Destination Code dialog box, enter a numeric number for the destination code and
click on the OK button.
13. Select the row representing the Destination Code entered in the previous step
14. Under Normal Route column, double click and enter the route entered in Step 4.
15. Under the Absorbed Length column, specify the number of digits that will be absorbed before
sending the rest of the digits to the service provider.

5.1.3. SIP Routing Table Configuration
There are two possible ways to configure the BCM to route outbound SIP calls to the Service Provider:
Æ
• Using the Routing Table tab found by clicking on IP Trunks module in Configuration
Æ
Resources
• Using the SIP Proxy tab found by clicking on IP Trunks module in Configuration
Æ
Telephony Resources.
This guide illustrates how to do it using the Routing table. For details of how to use the SIP Proxy tab, see
the BCM configuration guides.
1. Under Configuration
and click on the “Routing Table” tab.
2. Add a “Remote Gateway” by clicking on the “Add” button.
3. In the “Add Remote Gateway” dialog box that is displayed, configure the fields as follows:
Telephony Resources.
Æ
Resources Æ Telephony Resources; select module type “IP Trunks”
• Description: Enter the logical name for the trunk destination
• Destination Digits: Enter digits that identify the remote system as the call
destination.
• VoIP Protocol: SIP
• Domain: SIP Domain name of PAETEC. This will be provided by PAETEC
1
• IP Address: Provide the IP address of the SBC
• Port: Provide the optional UDP port number to which the BCM will send SIP
messages.
.
Æ
Resources
• GW Type: Set this field to Other.
• MCDN Protocol: Set to None.
• QoS Monitor: Leave unchecked
• Tx Threshold: Leave this field at its default value of 0.0
4. Click the OK button
1
This parameter is only required when configuring a SIP trunk between BCM and PAETEC’s BroadWorks SIP
server.

5.1.4. SIP Settings Configuration
1. Under Configuration
and click on the “SIP Settings” tab
2. In the SIP Settings sections:
• Local Domain: Leave blank
• Disable maddr in Contact: Checked to disable maddr in Contact header

Resources Æ Telephony Resources: Select module type “IP Trunks”
5.1.5. SIP Media Parameters Configuration
1. Under Configuration Æ Resources Æ Telephony Resources: Select module type “IP Trunks”
and click on the “SIP Media Parameters” tab.
2. In the Preferred Codecs section, configure G.729, G.711-uLaw as the first and second preferred
codec respectively.
3. In the codec Settings section, uncheck Enable Voice Activity Detection.
4. In the codec Settings section, select 20ms as the payload size for both G.729 and G.711
5. Again in the codec settings Section set G.711 as the Fax transport.
5.1.6. SIP Authentication Configuration

• Domain: Provide the SIP Domain name (provided by PAETEC) for PAETEC SIP
trunking service
• In the Account Identity section, select configure this SIP Account as either a Parent
or Child account. A Parent account can be used by BCM Phone to place out going
calls via the SIP Trunk between the BCM and PAETEC whereas as a Child account
can only be used by a given BCM Phone. A Parent account will work for most
deployments.
• Since authentication is not required for any of PAETEC SIP Trunking service, do not
configure the User Credentials section.

5.1.8. Configuring Incoming Calls from PAETEC to BCM
This can be done in one of two ways;
1. The DID associated with the PAETEC SIP account assigned to the BCM can be associated
with a target line assigned to a group of set(s) and all calls to the DID will be routed those
set(s).
2. All calls to the DID associated with the PAETEC SIP account assigned to the BCM can be
answered by the Auto Attendant (AA) and from there, a DN can be entered to reach a phone
on the BCM
5.1.8.1 Assigning DID to BCM Phones for Incoming Call
1. Navigate to ConfigurationÆ TelephonyÆ Lines Æ Target Line and click on an unused
target line
2. On the selected Target Line, set the “Pub. Received #” to the last 4-digis of the PAETEC
assigned DID.
3. Assign the DN of phones on the BCM that require an appearance on this target line. This will
be the phones that will be alerted when call to the PAETEC assign DID is received.
