Integrating ADTRAN eSBC and NEC SV8100
Configuring the ADTRAN eSBC
Step 3: Configure 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
Step 4: Enable Media Anchoring
Media anchoring is an eSBC feature that forces 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. 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.
