Interoperability Guide
Integrating an ADTRAN eSBC and
Avaya IP Office with a Verizon SIP Trunk
This interoperability guide describes an example configuration used in
testing the interoperability of an ADTRAN enterprise session border
controller (eSBC) and the Avaya IP Office private branch exchange
(PBX) using a Session Initiation Protocol (SIP) trunk to provide a SIP
trunk gateway to the service provider network. In this particular situation,
the service provider network is customized for Verizon. This guide
includes the description of the network application, verification summary,
and example individual device configurations for the ADTRAN eSBC
and the Avaya IP Office PBX products.

Application Overview
Application 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 wider area network (WAN) connection to the service provider network and
terminates the service provider SIP trunk, and 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 IP business gateway in a typical network deployment.

Figure 1. ADTRAN eSBC in the Network
Interoperability
The network topology shown in Figure 2 on page 3 was used for interoperability verification between the
ADTRAN eSBC, the Avaya IP Office, and the Verizon SIP network. 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 Avaya IP Office LAN interface
connects to the customer LAN. Two SIP trunks are configured on the ADTRAN eSBC gateway: one to the
Verizon SIP network and the second to the Avaya IP Office PBX. The ADTRAN 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 Avaya IP Office PBX supports various phone types (including digital, H.323, and SIP IP phones). The
phones register locally to the Avaya IP PBX. Dial plan configuration routes external calls through the SIP
trunk to the ADTRAN eSBC gateway.

As is recommended for operation on the Verizon SIP network, a diversion header with the main business
billing telephone number will always be included for calls to the Verizon network. The diversion header
will not be added if an emergency 911 call is placed. A SIP header manipulation rule is used to implement
this policy.

Step 10: Configuring the Double reINVITE Preference on page 11
Step 11: Configuring SIP Privacy (Optional) on page 11
Step 12: Configuring SIP OPTIONS Messages (Optional) on page 12
Step 1: Accessing 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.
If during the unit’s setup process you have changed the default IP address (10.10.10.1),
use the configured IP address.
3. Enter your user name and password at the prompt.
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.
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)#

ADTRAN eSBC, Avaya IP Office, and Verizon
Configuring the ADTRAN eSBC
Step 2: Configuring the Basic Network Settings
Basic network configuration includes setting up two Ethernet interfaces, one for the Ethernet LAN
interface to the Avaya IP Office PBX, 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 IP address for the
interface, and the media-gateway command is required on the interface for SIP and Realtime Transport
Protocol (RTP) media traffic.
When configuring the basic network settings, use the IP address information supplied by
the service provider.
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 192.0.2.1 255.255.255.192
(config-eth 0/1)#ip access-policy PUBLIC
(config-eth 0/1)#ip crypto map sip
(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 10.22.227.14 255.255.255.0
(config-eth 0/1)#ip access-policy PRIVATE
(config-eth 0/2)#media-gateway ip primary
(config-eth 0/2)#no shutdown
Step 3: Configuring Global Voice Modes for Local Handling
Configure the ADTRAN 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

Configuring the ADTRAN eSBC
Step 4: Enabling Media Anchoring
Media anchoring is an eSBC feature that routes RTP traffic through the ADTRAN 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. Enable the RTP symmetric filter
using the ip rtp symmetric-filter command. Enter the commands as follows:
(config)#ip rtp symmetric-filter
(config)#ip rtp media-anchoring
(config)#ip rtp media-anchoring transcoding dtmf
Step 5: Configuring Header Manipulation Rules
The following configuration example is specific to Verizon’s IP trunking product. For a generic example of
a basic eSBC configuration, refer to eSBC SIP Trunking Sample Configuration available online at
ADTRAN’s Support Forum, https://supportforums.adtran.com.
For a more complete discussion of SIP HMR policies and rule sets, refer to Manipulating SIP Headers and
Messages in AOS available online at ADTRAN’s Support Forum, https://supportforums.adtran.com.
To ensure voice activity detection (VAD) capabilities are explicitly disabled, a SIP header manipulation
rule (HMR) is added to the ADTRAN eSBC. This ensures all G.729 calls explicitly have the annexb
option set as =no.
Enter the commands as follows:
(config)#sip hmr GLOBAL out
(config)#hmr policy GLOBAL
(config-policy-GLOBAL)#rule-set ANNEXB 10
!
(config)#hmr rule-set ANNEXB
(config-rule-set-ANNEXB)#message-rule ANNEXBrule message-type any 10
(config-msg-rule-ANNEXBrule)#match header content-type match-value /application/sdp/
(config-msg-rule-ANNEXBrule)#modify body match-value "/(.*)a=fmtp:18 annexb=\w{2,3}\r\n(.*)/"
new-value /\1\2/ 10
(config-msg-rule-ANNEXBrule)#modify body match-value "/(.*a=rtpmap:18 G729.*)/" new-value
"/\1\na=fmtp:18 annexb=no/" 20
To create an HMR policy to strip diversion headers for 911 calls, enter the commands as follows:
(config)#hmr policy VERIZON
(config-policy-VERIZON)#rule-set e911 10
(config)#hmr rule-set e911
(config-rule-set-e911)#message-rule e911rule message-type request 10
(config-rule-set-e911)#match header to match-value sip:911@
(config-rule-set-e911)#remove header diversion position all 10

Configuring the ADTRAN eSBC
Step 6: Configuring 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 trunk is created using the voice trunk <Txx> type sip command. The description <text> command
is used to label the trunk. The match ani add diversion command is used to add a SIP diversion header to
be included to all calls to the Verizon network. The sip-server primary <ipv4 address | hostname>
command is used to define the host name or IPv4 address of the primary server to which the trunk sends
SIP messages. Additionally, the hmr out command is used to specify 911 calls are stripped of their
diversion headers (refer to Step 5: Configuring Header Manipulation Rules on page 8 for more
information).
Enter the commands as follows:
(config)#voice trunk T01 type sip
(config-T01)#description PROVIDER
(config-T01)#match ani "$" add diversion <MAIN BUSINESS NUMBER> unconditional no off
(config-T01)#sip-server primary <VERIZON SIP SERVER FQDN>
(config-T01)#domain <VERIZON DOMAIN NAME>
(config-T01)#trust-domain
(config-T01)#codec-list 729-711u-711a both
(config-T01)#grammar from host local
(config-T01)#grammar p-asserted-identity host local
(config-T01)#hmr VERIZON out
Step 7: Configuring the PBX SIP Trunk
The second voice trunk that must be configured is the SIP trunk to the Avaya IP Office from the ADTRAN
eSBC. Use the voice trunk <Txx> type sip command 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 SIP server’s primary IPv4 address (or host name).
Use the description <text> command to label the trunk. Use the sip-server-primary <ipv4 address |
hostname> command to set the server address to the Avaya IP Office LAN IP address.
In addition, the Avaya IP Office must control call transfers. This is accomplished using the
transfer-mode-network command in the trunk’s configuration. Use the grammar from host local
command 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 T02 type sip
(config-T02)#description PBX
(config-T02)#sip-server primary 10.22.227.1
(config-T02)#codec-list 729-711u-711a both
(config-T02)#grammar from host local
(config-T02)#transfer-mode network

ADTRAN eSBC, Avaya IP Office, and Verizon
Configuring the ADTRAN eSBC
Step 8: Configuring a Trunk Group for the Avaya IP Office
After configuring the two SIP trunks, configure an individual trunk group for the Avaya IP Office PBX
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
X
N
M
$
[]
,()
-
Match the exact digit(s) only
Match any single digit 0 through 9
Match any single digit 2 through 9
Match 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
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-PBX)#accept 719555923[0-4] cost 0
Step 9: Configuring a Trunk Group for the Service Provider
After configuring a trunk group for the Avaya IP Office PBX, create a trunk group for the service provider
trunk account. Create the trunk group 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 8: Configuring a Trunk Group for the Avaya IP Office on page 10.
Enter the commands as follows:
(config)#voice grouped-trunk VERIZON
(config-VERIZON)#trunk T01
(config-VERIZON)#accept $ cost 0
(config-VERIZON)#accept NXX-NXX-XXXX cost 0
(config-VERIZON)#accept 1-NXX-NXX-XXXX cost 0
(config-VERIZON)#accept 011-$ cost 0
(config-VERIZON)#reject 719555923[0-4]
Step 10: Configuring the Double reINVITE Preference
After configuring the trunks, trunk groups, and any media anchoring settings, determine whether a double
reINVITE is preferred globally for all calls in the system using the sip prefer double-reinvite command.
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 version of the sip prefer double-reinvite command from the Global
Configuration mode.
Enter the command as follows:
(config)#no sip prefer double-reinvite
Step 11: Configuring SIP Privacy (Optional)
The ADTRAN eSBC supports SIP user privacy by using the P-Asserted-Identity (PAI) SIP header. Enable
PAI and SIP privacy support by entering the ip sip privacy command from the Global Configuration mode
and by entering the trust-domain command for voice trunks (to add PAI). Enter the commands as follows:
(config)#sip privacy
(config)#voice trunk T01 type sip
(config-T01)#trust-domain
(config-T01)#exit
(config)#voice trunk T02 type sip
(config-T02)#trust-domain

ADTRAN eSBC Sample Configuration
Step 12: Configuring SIP OPTIONS Messages (Optional)
The Avaya IP Office supports sending SIP OPTIONS messages as a keep-alive check for the SIP line
connection to a SIP server. This SIP OPTIONS request is sent to an Unknown user. To respond to this
request, a virtual voice user 00000 may be configured on the ADTRAN eSBC using the SIP trunk
connection to the Avaya IP Office, T02.
Enter the commands as follows:
(config)#voice user 00000
(config-00000)#connect sip
(config-00000)#password “1234”
(config-00000)#did “XXXXXXX”
(config-00000)#sip-identity Unknown T02
ADTRAN eSBC Sample Configuration
The following configuration was used to validate the interoperability of the ADTRAN eSBC with the
Avaya IP Office and Verizon SIP trunking service.
The configuration parameters entered in this example are sample configurations only, and
only pertain to the configuration of the SIP trunking gateway functionality. This
application should be configured in a manner consistent with the needs of your particular
network. CLI prompts have been removed from the configuration example. This
configuration should not be copied without first making the necessary adjustments to
ensure it will function properly in your network.

Configuring the Avaya IP Office
Step 1: Installing Avaya IP Office Manager
Install the IP Office 500v base system as shown in the Network Topology diagram in Figure 2. Refer to the
IP Office Product Description guide for installation details. The LAN1 Ethernet interface connects to the
LAN switch (NetVanta 1534P). The IP Office 500v is equipped with a combination analog trunk module
(ATM). The ATM has 12 ports: 6 digital station ports (1 through 6), 2 analog station ports (7 through 8),
and 4 analog trunk ports (9 through 12).
IP Office configuration is performed using the IP Office Manager software client. IP Office Manager will
run on Windows 7 PC. The software and documentation are available for downloading from Avaya's
support website at www.avaya.com. Refer to the procedure in the IP Office Manager for how to install the
software.
When starting IP Office Manager, it attempts to connect to the Avaya IP Office 500v system. If the IP
Office Manager PC is on the same LAN subnet as the 500v, then the 500v will be discovered
automatically. Otherwise, the IP address for the 500v must be manually configured.
The login screen appears after connecting to the 500v. The password is set during installation (e.g.,
adtran).
