Your gateway doesn't have administration role. All you can do here is to reset what new username and password to manage your gateway. And it has all privileges to operate your gateway. You can modify “Web Login Settings” and “SSH Login Settings”. If you have changed these settings, you don’t need to log out, just rewriting your new user name and password will be OK. Also you can specify the web server port number. Usually the web login default mode is “http and https”. For safety, you can switch to “only https” mode.

There is an example for Routing rules number conversion, it transform calling, called number at the same time. Suppose you want eleven numbers start at 159 to call the eleven numbers of start at 136. Calling transform delete the three numbers from left, then writing number 086 as prefix, delete the last four numbers, and then add number 0755 at the end, it will show caller name is openvox China Telecom. Called transform adds 086 as prefix , and Change the last two number to 88.

Auto Provisioning
Auto provisioning or auto-configuration is an easy, flexible and time-saving way to upgrade firmware and configurations for E1 gateways in mass deployment. With auto provisioning, all user information can be entered via the central ACS (Auto Configuration Server). ACS can be DHCP server or TFTP, HTTP and FTP server. It will not take effects immediately but in the next time system is power on. It could be postponed the execution of restart system also.
Note that system will not be upgrade the firmware and update configurations if the connection between ACS and gateway is disconnect.
Preparation
The following should be prepared before anto provisioning being applied.
l Enable the auto provisioning in gateway
l The ACS has been prepared
l The network between gateway and ACS is connected
Configuring gateway
Usually, the feature is disabled before being on sale. To activate the auto provisioning function, please follow the procedures as below.
Step 1 On the ADVANCED-> Auto Provision interface
Step 2 Enable the ‘Enabled’ option and select ACS. DHCP option 66 can be enabled if ACS has been work as DHCP server, otherwise please select protocol of provisioning and fill the value of ‘Auto Config Server URL’. Username and password may need to be filled in FTP/HTTP for the purpose of system safety. Do not forget to select Firmware upgrade, upgrade mode and fill the value of timeout, and click ‘Save’.
Step 3 Set interval of checking in LOGS->System notice then enable it, and click ‘Save’.

Provisioning example
After auto provisioning is enabled, the gateway will visit the Auto Configuration Server and download the updated files periodically based on the timer Check Interval (LOGS->System notice). By default, the timer is set as every hour. System will receive a message from ACS, like figure 7-4-3, and the message will be display in the system notice (LOGS->System Notice).
Auto provisioning will not take effects immediately but in the next time system is power on. It could be postponed the execution of restart system also.
Now, an example of using Auto Provisioning will be given in the following.
- Activate the auto provision (TFTP) in ADVANCED-> Auto Provision like figure 7-4-4.
Figure 7-4-4 Auto provision settings
- Enable the check interval in LOGS->Log settings->System Notice like figure 7-4-5.

Notice:
The demo of E1 gateway mac address is A0:98:05:01:DB:CA (eth0), therefore the private configuration file is EPC-a0980501dbca.conf.

SNMP
Simple Network Management Protocol (SNMP) is an application–layer protocol, which is used to manage and monitor network elements and exchange management information between network devices. By default SNMP uses port 161 for communication.
Since the inception SNMP, it embraces three versions: v1, v2c and v3. V1 and v2c are the most implemented version of SNMP; v3 is target at the high security when compare to its older versions. The gateway support private SNMP MIBs (private enterprise number) to access.

A powerful, indispensable and easy-to-use MIB browser is convenient for engineer/manager to manage SNMP enabled network devices and applications. In this session, Manage Engine MIB browser is selected. It allows user to issue SNMP requests to retrieve agent's data, or make changes to the agent. It is free tool for Windows, Mac and Linux.

After the rest field has been filled, then verify it. Click Operations->GET to get the value of system location and it returns the value which we just set.
(2). Set SNMP parameters via SNMP MIB browser. For example, set the system name. system name is “dgw100x” by default, then set it as “VoIP gateway”. See figure 7-5-4.
- Click Operations->GET to attain the current system name.
- Fill the field of Set Value with “VoIP gateway”.
- Click Operations->SET to set the system name.
- Click Operations->GET to attain the modified system name.

TR069
TR069 is a remote management solution which offers a single interface to manage the ACS and automate the deployment and support of data, voice and video services, thereby reducing operation and support costs, while enhancing customer satisfaction. Its user-friendly interface covers the entire service lifecycle, from centralized remote provisioning of services, to inventory management, group updates, monitoring, event triggering, and support automation. Figure 7-6-1 is TR-069 configuration interface and table 7-6-1 is its definition.

Network Capture
The gateway have been supplied a network packets capture in the web for ease of user to analysis, capture and monitor the gateway’s network status, RTP flows, protocol analysis and so on.
Table 7-7-1 Definition of Network capture
Options | Definition |
Network Interface | Specify which interface to be capture packets from. ‘All’ means capture packets from all interfaces |
Source host | Specify which source host IP address to listen for |
Destination host | Specify which destination host IP address to listen for |
Port | To specify a port that is either source or destination direction |
Protocol | To specify which protocol to be captured, ‘All’ stands for capture multi-protocols, the SIP default port is 5060, If you are using a different port, please amend it. |
The interface is in ADVANCED->Network Capture.

8. Logs
On the “Log Settings” page, you should set the related logs on to scan the responding logs page. For example, set “SIP Logs” on like the following, then you can turn to “SIP” page for sip logs, otherwise, sip logs is unavailable. And the same with other log pages.

Call Statistics
The figure of call statistics, you’ll find “Answered”, “congestion”, “Call busy”, “Call failed”, “No answer”, “Current calls”, “accumulated calls”, “Calls duration” and “ASR”. “ASR” stands for Answer Seizure Ratio. “Calls duration” will count the whole calls in the gateway. The call statistics will be saved before power off. It will be loaded after power on. It can be refreshed by itself. You can reset the statistics manually.
Figure 8-4-1 Call Statistics
Note: Do not forget to enable call statistics in “Log Setting” if you want to statistics the calls.
System Notice
The system notice could be generated by system to inform the network manager of what is going on if it has been enabled. Firmware upgrade messages from official website and auto provisioning messages from ACS are main notice right now. And at first, enable the system notice function like figure 8-5-1.
Figure 8-5-1 enable system notice function
After about an hour, a system message is received in the web like 8-5-2.
