1 Overview
1.1 Product Introduction
MX8A and HX4E Series intelligent VoIP Gateways (MX Gateways) are designed to bridge the
traditional telecom terminal device into IP networks through SIP or MGCP protocols. The main
applications include:
For carriers and value-added service providers to provide telephone, fax and voice-band data services
to subscribers using IP access methods such as FTTB, HFC, and ADSL;
Used to bridge the traditional telecom terminal equipment, such as PBXs, to the VoIP core networks
of carriers;
Connected with an enterprise PBX to provide IP-based voice private network solutions for institutions,
enterprises and schools;
Used as remote access equipment for IP-PBXs in call center deployment
The basic hardware specifications for the MX8A/HX4E are included in Table 1-1.

Hardware for MX series gateways uses high-performance CPUs, ensuring that each product of the series
can achieve full-capacity concurrent calls with high speech quality.
MX gateways software adopts the stable and reliable embedded Linux operating system (OS),
implementing scores of business phone functions, including, call forwarding, call transfer, call hold,
teleconference, caller identification, Do Not Disturb, ringback tone, hunt group simultaneous ring,
distinctive ring, one phone with two numbers, and fax. In addition, MX gateways are featured with FXO
port second stage dialing with voice prompt, routing table with a maximum of 500 entries, phone digit
manipulation, and PSTN failover upon power-off or network disconnection.
MX gateways support local and remote management operations through Web GUI or Telnet/SSH,
support SNMPv2-based and TR069/TR104/TR106-based centralized management schemes, and support
auto provision. Maintenance tasks such as modifying configuration, upgrading software, collecting
statistical data, downloading logs, and fault alarms can be performed.

2.1.1 Obtaining Gateway IP Address
MX8A/HX4E Gateways start DHCP service by default, and automatically obtain an IP address on the
LAN; you can use the factory-default gateway IP address if it is unable to be obtained (e.g. when
connected directly with a computer).
To change the fixed IP address, you can use a telephone connected to the FXS port to dial *90+the fixed
IP address+#subnet mask#IP address of the gateway#0#. The dots "." in the IP address need to be
replaced with star keys "*".
To obtain an IP address through DHCP, you can use a telephone connecting to the FXS port to dial
*90###1#, and after "The feature is now activated. " is heard, restart the device.

You can dial ## to obtain the current gateway IP address, version information of firmware and port
used to access the Web GUI using the telephone connected to the subscriber line (FXS ports) after the
equipment is powered on.
If the device does not have FXS ports (such as an MX8A-8FXO or HX440E), you can use New
Rock's device IP address obtaining tool called "Finder" to obtain the IP address.
You can get the "Finder" software by sending email to [e-mail].

DHCP: use the dynamic host configuration protocol (DHCP) to obtain IP addresses
and other network parameters;
PPPoE: PPPoE service is used.
Username
Enter an authentication user name if PPPoE service is selected, and there is no default
value.
Password
Enter an authentication password if PPPoE service is selected, and there is no default
value.
IP address

will use the IP address filled in here. If the gateways obtain an IP address through
DHCP, the system will display the current IP address automatically obtained from
DHCP. This parameter must be set due to no default value.
Subnet mask
The subnet mask is used with an IP address. When the gateways uses a static IP
address, this parameter must be entered; when an IP address is automatically obtained
through DHCP, the system will display the subnet mask automatically obtained by
DHCP. It has no default value.

detection of the change of the public IP address of the device by using STUN query.
Normally, the session interval of STUN request should be shorter than the
registration period.
Note: The IP address obtained through STUN is used only for re-registration of SIP
server, and it is not used in SIP message fields such as Via and Contact and SDP C
field.
Trunk re-registration & NAT address updating:A re-registration of the SIP
trunk is triggered upon the detection of the change of the public IP address of the
device by using STUN query. And the IP address obtained through STUN is used in
