Select the landing gateway, double-click the information of the landing gateway group -> Click... -> Add -> Double-click the default one and then select one (select Apply after setting, otherwise it will not be saved).
   • View Your Own Phones: Business Management -> Phone Business -> Phone Management -> Filter (you can fill in the phone number in the filter).
   • eyeBeam Phone Settings: Display Menu -> SIP Account Settings -> Add. Display Name: Set the phone number for hang-up management by yourself. Username: The phone's own number. Password: The phone management phone number. Authorized User: The phone's own number. Domain Name: The IP address of the number that needs to be tested (the IP address for logging into VOS).
   • Testing Communication:
     • System -> Account Management -> Select Settlement Account for Account Type -> Filter.
     • Double-click to enter the account that needs to be tested, and double-click the number of network managers to enter.
     • Click Edit -> Landing Prefix, copy the main calling prefix of the landing (if there are multiple ones, just copy one).
     • Fill in the copied number into the outgoing call display of phone management, and copy the network manager group to the network manager group of the phone.
     • Add SIP to the eyeBeam phone and then you can make calls.

2. Configuration Steps for Building the VOS3000 Internet Telephone System:

   • Obtain VOS3000 Software: Obtain the VOS3000 software installation package through formal channels. VOS3000 is commercial software and requires purchasing an authorization.
   • Prepare the Server: Prepare a dedicated server. The operating system usually recommends choosing Linux, such as CentOS or Ubuntu versions, etc. Ensure that the server has sufficient hardware resources, such as CPU, memory, and storage space.
   • Install the Operating System: Install the selected Linux operating system on the server and conduct basic system configuration and security settings.
   • Install VOS3000 Software: Run the VOS3000 software installation package and follow the installation wizard to install it. You need to provide the authorization key obtained when purchasing the software.
   • Configure Network and Ports: Configure the network settings and ports on the server to ensure that the server can communicate with the external network and open the required ports, such as the SIP port (usually 5060), the management port (such as 8888), etc.
   • Conduct System Settings: Run the management interface of VOS3000, which can usually be accessed in a Web browser. When logging in for the first time, you need to modify the default password and conduct necessary system settings, such as time zone, domain name, etc.
   • Create Users and Routes: According to business requirements, create user accounts and set call routes and billing strategies, which will determine how users make calls and the charging standards, etc.
   • Security Settings: In order to protect system security, some security measures can be taken, such as restricting access to the management interface, configuring firewalls, and enabling logging, etc.
   • Testing and Optimization: After completing the above settings, conduct system testing and optimization to verify that users can make and receive calls normally and check whether the system runs stably.
   • Provide Technical Support: Once the system is built, technical support can be provided to users to ensure that there is sufficient knowledge and experience to handle users' problems and troubleshoot.

3. Configure Ignore Prefix for Non-Standard 11-Digit Mobile Phone Numbers (Taking the VOS3000 Outbound Call System as an Example):

   • Log in to the VOS3000 Management Interface: Log in using the administrator account.

   • Set Ignore Prefix:

     • Softswitch Management Settings: After logging in, find the Supplementary Settings option in the softswitch management, enter the system parameter configuration interface, find the system parameter named SS_NON_STANDARD_PREFIX, and fill in a specific value in this parameter, for example, 999. In this way, when the system encounters a non-standard mobile phone number starting with 999, it will automatically ignore this prefix and then recognize and process the subsequent numbers.

     • Business Configuration: Enter the business configuration interface, find the Domestic Business Rule Settings option, and set parameters such as number length and number prefix in this option to ensure that the system can correctly recognize non-standard 11-digit mobile phone numbers. Also set the ignore prefix in the domestic business rules to cooperate with the previous softswitch management settings.

   • Set Black and White Lists: When adding black and white list rules, also set the ignore prefix so that when the system checks whether the phone number is in the black and white lists, it will automatically ignore the prefix of non-standard mobile phone numbers, thus ensuring the accuracy of the black and white list functions.

   • Save Settings and Test Verification: After completing the above configurations, save the settings and ensure that the modifications take effect, and then conduct test verification.

4. VOS3000 Client Incoming Call Configuration (Taking Super Simple Five Steps as an Example):

   • View SIP Proxy: In the registration management, view the SIP proxy IP address registered by your line, and record it.
   • Create a Normal Account: Create a normal account for incoming calls, select "Billing Rate", and choose the rate according to your own situation. For testing here, a free rate is configured. If the rate is not free, you need to recharge this normal account.
   • Newly Build a Docking Gateway: Newly build a docking gateway, click the "Supplementary Settings" of this gateway, select "Gateway Type" as static IP, and then fill in the SIP proxy IP address recorded in the registration management in the IP address field.

4. What Protocol Types of Calls Does the VOS3000 System Support?

The VOS3000 system supports calls of multiple protocol types, including but not limited to the following:

Meanwhile, use antivirus software and vulnerability scanners to ensure that there are no security vulnerabilities in the system software and application programs.

• Strengthen Password Policies: Strengthen the password policies for VOS3000 user accounts. For example, set complexity rules such as minimum length, special characters, numbers, and uppercase and lowercase letters to ensure that passwords are strong enough. Regularly changing passwords is also a recommended security practice.

• Restrict Interface Access: The remote management interface of the VOS3000 is a very important part and should be restricted to specific IP addresses. Clearly limit the source IP addresses that can access the management interface to prevent unauthorized users from accessing the VOS3000 management interface.

• Monitor Logs: Regularly check the system and application program logs of the VOS3000 to look for security events and abnormal behaviors in the system. This helps to discover potential risks and take timely measures to prevent further losses.

• Isolate Important Services: Isolate important services on independent servers to facilitate security isolation and restrict access to important services. Ensure that only authorized administrators can perform relevant operations.

• Improve System Throughput: Formulate load balancing strategies to filter malicious requests and improve system throughput to deal with attacks.

• Cooperate with Hosting Providers: Contact the VPS provider, inform them that your server is under a DDoS attack, and seek their help and support.

These measures jointly form the security protection system of the VOS3000 system, aiming to prevent unauthorized access or attacks and protect the stable operation of the system and the security of user data.
