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 โ 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.
