📌 Multiple IP License in VOS3000 – Complete Guide for Same Server Deployment

VOS3000 is one of the most widely used Chinese softswitch platforms in the wholesale VoIP industry. Its popularity comes from its ability to handle bulk call volume, junk traffic, and high CPS environments while consuming comparatively low server resources.

In this guide, we will explain in detail how Multiple IP License in VOS3000 works, why IP-based licensing exists, how public and private IP can be used together, and what you must know before installing or renting VOS3000.

🔐 How VOS3000 License Works

VOS3000 license is hardware-bound. It is not only limited to a simple serial key.

A VOS3000 license is generated based on:

• 🧩 Server IP Address
• 🧩 MAC Address
• 🧩 Other hardware parameters

This means only the IP addresses included inside the license file at installation time are allowed to process calls.

⚠️ If you add a new IP to the server later that was not included in the license, that IP will not be able to run calls.

🌐 Multiple IP License in VOS3000 – What Does It Mean?

Many VOS3000 users assume that only one IP can be licensed per server. This is not true.

👉 In reality, VOS3000 can support multiple licensed IPs on the same server.

We can license:

• ✅ Multiple public IPs
• ✅ Multiple private IPs
• ✅ A mixed combination of public + private IPs

For example:

• 🌍 3 Public IP + 2 Private IP = 5 IP licensed together
• 🌍 5 Public IP only
• 🌍 5 Private IP only

All licensed IPs can:

• 📞 Send calls
• 📞 Receive calls
• 📞 Be selected independently in routing gateway

🏳️ Why Clients Need Public + Private IP Together

In many countries, SIP trunk providers or telecom operators:

• 🚫 Do not allow public IP based SIP authentication
• 🚫 Only allow private IP (LAN/MPLS/VPN based SIP)

In such cases:

• 🌐 Public IP is used for global routing or international carriers
• 🏠 Private IP is used for local SIP trunks or domestic gateways

This is where Multiple IP License in VOS3000 becomes extremely important.

Using both IP types in the same VOS3000 server allows:

• 🔀 Country-specific routing
• 🔀 Operator-specific IP binding
• 🔀 Better call success rate
• 🔀 Compliance with local telecom rules

⚙️ IP Selection in VOS3000 Routing Gateway

VOS3000 provides a built-in option to select:

• 📡 Which IP will be used to send calls
• 📡 Which IP will be bound with routing gateway

Inside the routing gateway configuration, you will see:

• ✔️ All licensed IPs listed
• ❌ Unlicensed IPs will not appear

This makes routing control:

• 🎯 Accurate
• 🎯 Predictable
• 🎯 Safe for billing and CDR

🛠️ Best Practice for Multiple IP License

✔️ Best practice: All IP addresses should be added to the server before installing VOS3000.

Why?

• 🧠 License file is generated at installation time
• 🧠 Missing IP means re-licensing required
• 🧠 Avoid downtime and license regeneration

⚠️ Adding IP after installation without re-license = IP will not work for calls.

🏢 One-Time Installation vs Rental Server

🔹 One-Time Installation

• ✔️ Multiple IP license supported
• ✔️ Public + private IP combination possible
• ✔️ Fully customized license

🔹 Rental Server

• ⚠️ Usually single IP only
• ⚠️ Shared infrastructure
• ⚠️ License scope limited

Rental server is a different business model and not comparable with custom multi-IP installation.
