This document covers basic set up of the following Media Gateway models MG4/S, MG8/S, MG4/O,
MG8/O, MG8/SO (MG will designate any model in this series) in conjunction with the MX250 and MX30.
This document is based on MG gateways with software revision 1.9.82.306.X and MX system with
software revision 6.0.
It is assumed the reader is familiar with creating Users, Devices, Assignments, SIP Servers on the MX
system and is a current ZCSE Technician. Basic Telephony and Basic Networking is assumed as well.
Consult “Media Gateway installation Guide” for installation procedures. Consult “MG User Configuration
Guide”for description of features not present in this manual.
It is strongly recommended that the MX is configured PRIOR to integrating the Media Gateways to prevent
the IP address of the Media Gateway being blocked by the MX.
MG Gateways must be configured with Microsoft® Internet Explorer®. At this time, FireFox®, Safari® and
other internet browsers are not supported by the current revision of MG Gateway software.

2Configure all ports on the MG
You MUST configure all ports on the MG, if you fail to configure all ports (even if
you are not using them) the MG will continue to attempt to register, this action
devices to block the IP of the MG itself.
3MX250/30 Setup
It is recommended that the MX have a generic SIP device created for each FXS Port
that is on the MG to register against. The Device ID used in the MX will be the
phone number used on the MG for registration purposes; this configuration does
not count against any licensing, as the MX is not licensed by registration.
3.1 Create Users
Create a user for each FXS (SLT) port of the MG gateway by logging into the MX
Admin UI and navigating to Configure | Users.

3.2 Create Devices for FXS/FXO Ports
Create a device for each FXS/FXO port of the Gateway by navigating to Configure |
Devices in the Admin UI. Each step is outlined below. Since you are creating
Generic SIP devices no restart of the MX is needed. You will not be using the FXS
configuration portion of the MX Admin UI, as the devices connected to Media
Gateways are connected as SIP devices.
3.2.1 Create new Generic SIP Profile
Before creating devices for Gateway from the Manage Device screen click the
Profiles button, and create a new Generic SIP profile.
From the dropdown select Generic SIP device, and give the profile a unique name.

We recommend assigning users to the devices associated with FXS ports of MG
only.
4Connecting the Computer to MG Gateway
To configure the MG Gateway, use the web interface.
Use the Ethernet cable that comes with the system to connect MG to the network
By default the MG8 uses DHCP and can accept the IP address from DHCP
automatically. If there is no DHCP server on the network, you can use factory
default IP address of 192.168.2.218. After the MG8 is started (when leds stop
flashing), it will repeat the IP address to the first off-hook user; in addition, you can
dial ## from any analog phone connected to the FXS Ports to have the MG play its
IP. If there is only FXO ports use external call and dial ## after been connected.
From the PC that is on the same network as MG8, open Internet Explorer, no other
browsers are supported at this time. Enter the gateway IP address in the Address
field (for example, 192.168.2.218). On the login page enter the gateway password
(the default password is voip, which can be changed on the page Changing
Password), and you enter the web configuration interface.

6Basic Settings
Basic settings are where you set the IP addressing and SIP Registrations settings. SIP
registration settings for the FXS/FXO port MUST be set LAST, to prevent the MX
from blocking the IP address of the MG8. If the IP address is blocked by the MX (a
syslog event will be generated) you must restart them MX to remove this block.

First digit
timer
parameter after offhook, the gateways will consider that the subscriber
has given up the call and prompt to hang up in busy tone. Unit: second;
Default value: 12 seconds.
Inter-digit
timer
dialing the last number key to the set time by this parameter, the
gateways will consider that the subscriber has ended dial-up and call out
the dialed number. Unit: second; Default value: 12 seconds.
Critical digit
timer
This parameter is used with the "x.T" rule set in dialing rules. For
example, there is "021.T" in the dialing rules table. When a subscriber
this parameter (eg. 5 seconds), the gateways will consider that the
subscriber has ended dial-up and call out the dialed number 021.
Unit: second; Default value: 5 seconds.
Codec
Codecs methods supported by the gateways include G729A/20,
G723/30, PCMU/20, PCMA/20, iLBC/30 and GSM/20 (as shown in
table 2-5). This parameter must be set due to no default value.
Several encoding methods can configure in this item at the same time,
platform in the order from front to back when configuring the codec
methods
Hook-flash
handle
The gateways provide the following processing modes after detecting
hook flash from subscriber terminals: processing the hook flash
internally; transmitting the hook flash to platform with RFC 2833, and
transmitting the flash-off to platform with SIP INFO.
DTMF method
Transmission modes of DTMF signal supported by the gateways include
Audio, RFC 2833 and SIP INFO. The default value is Audio.
Audio: DTMF signal is transmitted to the platform with sessions;
SIP INFO: Separate DTMF signal from sessions and transmit it to the
platform in the form of SIP INFO messages;
RFC 2833: Separate DTMF signal from sessions and transmit it to the
platform through RTP data package in the format of RFC2833.
2833 payload
type
value of 2833 payload type is 100. The effective range available: 96 ~
127. This parameter should match the setting of far-end device (eg.
platform).
DTMF on-time
This parameter sets the on time (in ms) of DTMF signal sent from FXO
port. The default value is 100 ms. Generally, the duration time should be
set in the range of 80 ~ 150 ms.
