Overview
Service providers are increasingly using SIP trunks to provide Voice over IP (VoIP) services to customers.
ADTRAN eSBC products provide features that normalize the SIP signaling and media between the
customer’s PBX and the service provider’s SBC and softswitch server. In this application, the ADTRAN
eSBC gateway operates as a SIP back-to-back user agent (B2BUA). One Ethernet interface on the
ADTRAN eSBC provides the wide area network (WAN) connection to the service provider network and
terminates the service provider SIP trunk. A second Ethernet interface connects the customer’s local area
network (LAN) and provides a SIP trunk connection to the IP PBX for VoIP applications. Figure 1
illustrates the use of the ADTRAN eSBC in a typical network deployment.

Interoperability
The network topology shown in Figure 2 on page 3 was used for interoperability verification between the
ADTRAN eSBC and the NEC SV8100. The configuration is a typical SIP trunking application, in which
the ADTRAN eSBC gateway Ethernet interface provides the Ethernet WAN connection to the service
provider network. It should be noted that the WAN connection is not limited to Ethernet. A second
Ethernet interface connects to the customer LAN. The NEC SV8100 connects to the customer LAN. Two
SIP trunks are configured on the ADTRAN eSBC gateway: one to the service provider SIP network and
the second to the NEC SV8100. TheADTRAN eSBC gateway operates as a SIP B2BUA, and outbound
and inbound calls to the public switched telephone network (PSTN) are routed through the ADTRAN
eSBC.
The NEC SV8100 supports various phone types, including digital, H.323, and SIP IP phones. The phones
register locally to the NEC SV8100. Dial plan configuration routes external calls through the SIP trunk to
the ADTRAN eSBC gateway.

Configuring the ADTRAN eSBC
The following sections describe the key configuration settings required for this solution. These settings are
implemented using the ADTRAN Operating System (AOS) command line interface (CLI).
To configure the ADTRAN eSBC for interoperability with the NEC SV8100 PBX, follow these steps:
•Step 1: Access the eSBC CLI on page 4
•Step 2: Configure the Basic Network Settings on page 5
•Step 3: Configure Global Voice Modes for Local Handling on page 6
•Step 4: Enable Media Anchoring on page 6
•Step 5: Configure the Service Provider SIP Trunk on page 6
•Step 6: Configure the PBX SIP Trunk on page 6
•Step 7: Configure a Trunk Group for the Service Provider on page 7
•Step 8: Configure a Trunk Group for the NEC SV8100 on page 8
•Step 9: Configure the Double reINVITE Preference on page 8
•Step 10: Configure SIP Privacy (Optional) on page 9
Step 1: Access the eSBC CLI
The AOS unit can be managed using the console port, Hypertext Transfer Protocol (HTTP), HTTP Secure
(HTTPS), Telnet, and Secure Shell (SSH). Most of the initial configuration is performed through the
console port or Telnet session. Accessing the AOS unit is described in this step.
To access the CLI on your AOS unit, follow these steps:
1. Boot up the unit.
2. Telnet to the unit (telnet <ip address>), for example:
telnet 10.10.10.1.

3. Enter your user name and password at the prompt.
4. Enable your unit by entering enable at the prompt as follows:
>enable
5. If configured, enter your Enable mode password at the prompt.
6. Enter the unit’s Global Configuration mode as follows:
#configure terminal
(config)#
Step 2: Configure the Basic Network Settings
Basic network configuration includes setting up two Ethernet interfaces, one for the Ethernet LAN
interface to the NEC SV8100, and the second for the Ethernet WAN interface to the service provider. Both
interfaces are configured using the ip address <ipv4 address> <subnet mask> and media-gateway ip
primary commands. The ip address command configures a static IPv4 address for the interface, and the
media-gateway command is required on the interface for SIP and Realtime Transport Protocol (RTP)
media traffic.
Enter the commands from the Ethernet interface configuration mode as follows:
For the WAN:
(config)#interface ethernet 0/1
(config-eth 0/1)#description WAN
(config-eth 0/1)#ip address 203.0.113.2 255.255.255.252
(config-eth 0/1)#media-gateway ip primary
(config-eth 0/1)#no shutdown
For the LAN:
(config)#interface ethernet 0/2
(config-eth 0/2)#description LAN
(config-eth 0/2)#ip address 192.168.1.1 255.255.255.0
(config-eth 0/2)#media-gateway ip primary
(config-eth 0/2)#no shutdown
If during the unit’s setup process you have changed the default IP address (10.10.10.1),
use the configured IP address.
The AOS default user name is admin and the default password is password. The default
enable password is password. If your product no longer has the default user name and
passwords, contact your system administrator for the appropriate user name and
passwords.
When configuring the basic network settings, use the IP address information supplied by
the service provider.

Step 3: Configure Global Voice Modes for Local Handling
Configure theADTRAN eSBC to use the local mode for call forwarding and transfer handling. By default,
both of these functions are handled by the network. To change these settings, use the voice transfer-mode
local and voice forward-mode local commands. Enter these commands from the Global Configuration
mode. By using the local parameter, both commands specify allowing the unit to handle call forwarding
and transfers locally.
Enter the commands as follows:
(config)#voice transfer-mode local
(config)#voice forward-mode local
Step 4: Enable Media Anchoring
Media anchoring is an eSBC feature that forces RTP traffic through theADTRAN eSBC gateway.
Minimum configuration for media anchoring includes enabling the feature using the ip rtp
media-anchoring command from the Global Configuration mode. The RTP symmetric filter works in
conjunction with media anchoring to filter nonsymmetric RTP packets. The RTP symmetric filter is
enabled using the ip rtp symmetric-filter command.
Enter the commands as follows:
(config)#ip rtp media-anchoring
(config)#ip rtp symmetric-filter
Step 5: Configure the Service Provider SIP Trunk
The first of two voice trunks that must be configured is the SIP trunk to the service provider from the
ADTRAN eSBC. Check with your service provider for any specific requirements beyond those listed in
this document. Your service provider will provide you with the IP addresses or fully qualified domain
name (FQDN) and possibly the port numbers for their SIP server. They may also provide a backup or
secondary SIP server.
The voice trunk <Txx> type sip command is used to define a new SIP trunk and activate the Voice Trunk
Configuration mode for the trunk. From the Voice Trunk Configuration mode, you can provide a
descriptive name for the trunk and define the IP address (or host name) of the SIP server. The description
<text> command is used to label the trunk. The sip-server primary <ip address | hostname> command
is used to define the host name or IP address of the primary server to which the trunk sends SIP messages.
Enter the commands as follows:
(config)#voice trunk T01 type sip
(config-T01)#description PROVIDER
(config-T01)#sip-server primary sip.example.com
Step 6: Configure the PBX SIP Trunk
The second voice trunk that must be configured is the SIP trunk to the NEC SV8100 from the ADTRAN
eSBC. The voice trunk <Txx> type sip command is used to define a new SIP trunk and activate the Voice
Trunk Configuration mode for the individual trunk. From the Voice Trunk Configuration mode, you can
provide a descriptive name for the trunk and define the IP address (or host name) of the PBX. The
description <text> command is used to label the trunk. The sip-server-primary <ip address | hostname>
command is used to set the server address to the NEC SV8100 LAN IP address.

6AOSSG0027-42A Copyright © 2015 ADTRAN, Inc. 7
In addition, the NEC SV8100 must control call transfers. This is accomplished using the
transfer-mode-network command in the trunk’s configuration. The grammar from host local command
is used to specify that the IP address of the interface is used in the SIP From header for outbound messages.
Enter the commands as follows:
(config)#voice trunk T11 type sip
(config-T11)#description PBX
(config-T11)#sip-server primary 192.168.1.2
(config-T11)#transfer-mode network
(config-T11)#grammar from host local
Step 7: Configure a Trunk Group for the Service Provider
After configuring the two SIP trunks, configure an individual trunk group for the service provider trunk
account. The previously created trunks are added to the trunk group, which is then used to assign outbound
call destinations (local calls, long distance calls, etc.). A cost is also assigned to each accept template in
the trunk group.
Use the voice grouped-trunk <name> command to create a trunk group and to enter the Voice Trunk
Group Configuration mode. The trunk <Txx> command adds an existing trunk to the trunk group, so that
outbound calls can be placed out that particular trunk. The <Txx> parameter specifies the trunk identity
where xx is the trunk ID number.
Use the accept <pattern> command to specify number patterns that are accepted for routing calls out of
the trunk. Use the no form of this command to remove a configured dial pattern. The <pattern> parameter
is specified by entering a complete phone number or using wildcards to help define accepted numbers.
Valid characters for templates are as follows:
0 - 9 Match the exact digit(s) only
XMatch any single digit 0 through 9
NMatch any single digit 2 through 9
MMatch any single digit 1 through 8
$Match any number string dialed
[] Match any digit in the list within the brackets (for example, [1,4,6])
,() Formatting characters that are ignored but allowed
-Use within brackets to specify a range, otherwise ignored
The following are example template entries using wildcards:
1) NXX-XXXX Match any 7-digit number beginning with 2 through 9
2) 1-NXX-NXX-XXXX Match any number with a leading 1, then 2 through 9, then any 2 digits,
then 2 through 9, then any 6 digits
3) 555-XXXX Match any 7-digit number beginning with 555
4) XXXX$ Match any number with at least 5 digits
5) [7,8]$ Match any number beginning with 7 or 8
6) 1234 Match exactly 1234

Integrating ADTRAN eSBC and NEC SV8100 Configuring the ADTRAN eSBC
6AOSSG0027-42A Copyright © 2015 ADTRAN, Inc. 8
Some template number rules:
1. All brackets must be closed with no nesting of brackets and no wildcards within the brackets.
2. All brackets can hold digits and commas, for example: [1239]; [1,2,3,9]. Commas are implied between
numbers within brackets and are ignored.
3. Brackets can contain a range of numbers using a hyphen, for example: [1-39]; [1-3,9].
4. The $ wildcard is only allowed at the end of the template, for example: 91256$; XXXX$.
Enter the commands as follows:
(config)#voice grouped-trunk PROVIDER
(config-PROVIDER)#trunk T01
(config-PROVIDER)#accept NXX-NXX-XXXX cost 0
(config-PROVIDER)#accept 1-NXX-NXX-XXXX cost 0
(config-PROVIDER)#accept 011-$ cost 0
(config-PROVIDER)#accept 411 cost 0
(config-PROVIDER)#accept 611 cost 0
(config-PROVIDER)#accept 911 cost 0
Step 8: Configure a Trunk Group for the NEC SV8100
After configuring a trunk group for the service provider, create a trunk group for the NEC SV8100 trunk
account using the voice grouped-trunk <name> command.Add an existing trunk to the trunk group
using the trunk <Txx> command. The outbound allowed calls are defined using the accept <pattern>
command and are assigned a cost using the cost parameter, as described in
Step 7: Configure a Trunk Group for the Service Provider on page 7.
Enter the commands as follows:
(config)#voice grouped-trunk PBX
(config-PBX)#trunk T11
(config-PBX)#accept $ cost 0
Step 9: Configure the Double reINVITE Preference
The sip prefer double-reinvite command is used from the Global Configuration mode to specify that a
double reINVITE is preferred globally for all calls in the system. Calls that typically require a double
reINVITE are forwarded calls and attended transfers. When these calls connect, a double reINVITE is
initiated.
By default, the system is configured so that double reINVITEs are preferred. If a transfer call involves a
SIP trunk operating in the local transfer mode, a double reINVITE is executed regardless of this preference
setting. To avoid extra SIP messaging in situations where it is not necessary, set this feature to not prefer
double reINVITEs by entering the no form of the sip prefer double-reinvite command from the Global
Configuration mode.
Enter the command as follows:
(config)#no sip prefer double-reinvite

Step 10: Configure SIP Privacy (Optional)
The ADTRAN eSBC supports SIP user privacy using the Privacy and P-Asserted-Identity (PAI) SIP
headers. The sip privacy command is used from the Global Configuration mode to enable SIP privacy
support. The trust-domain command is used from the Voice SIP Trunk Configuration mode to connect the
trunk to a trusted domain and enable PAI support, adding security measures for user’s identity and privacy.
Enter the commands as follows:
(config)#sip privacy
(config)#voice trunk T01 type sip
(config-T01)#trust-domain
(config)#voice trunk T11 type sip
(config-T11)#trust-domain

Configuring the NEC SV8100
The NEC SV8100 PBX is configured using NEC's PCPro Manager Software that runs on a Microsoft
Windows PC. The SV8100 also supports web access. However, ADTRAN recommends using the client
software for better performance. Refer to the NEC documentationfor detailed instructionson configuring
additional features and capabilities. The following sections describe the minimum configuration required
for SIP trunking interoperabilitywith theADTRAN eSBC.
