Introduction & Licensing

Installing 3CX Phone System as a Virtual PBX Server

3CX Phone System allows you to host up to 25 separate 3CX Phone System virtual PBX instances on one Windows Server 2012 machine. Each instance is entirely separate from the other and allows you to completely separate configurations and data between customers.

By hosting 25 Virtual PBX instances on one Windows Server machine, you can avoid having to license & manage individual Windows instances, saving greatly on licensing, management, operating system overhead and hardware costs.

Connect each instance to its own dedicated SIP trunk or Gateway port and keep call billing perfectly separated for each customer. The feature set of 3CX Phone System is almost identical whether you install it as a Virtual PBX in the cloud or as an on premise edition.

3CX Phone System allows you to easily deploy and manage 3CX Phone System Virtual PBXs:

Backup / Update all 3CX Phone System Virtual PBX instances

3CX offers a tool that is able to backup or update ALL instances on the machine and restore all instances on another machine if need be. Automate backup on a scheduled basis and restore all instances in case of hardware failure.

Full VMware and Hyper V compatibility

If you want to leverage your existing Vmware or Hyper V knowledge you can do so with 3CX Phone System. It has been verified and tested against the leading virtualization platforms and allows you to take full advantage of VMware and Hyper V management and redundancy features.

Easily configure a new 3CX Phone System Virtual PBX

Ability to quickly create a 3CX Phone System configuration using our wizard or from a web input form: Import users, configure trunks and push out to a new 3CX Phone System instance.

Allow companies to manage user settings with granular user access

Allow customers to manage their own extensions, but not Trunk, Gateway and other system configurations. Two additional user levels: Department manager, who can manage the extensions of his/her group, and System manager, who can manage all extensions. The System administrator level allows the customer full access to the system and can be disabled to avoid any misconfigurations by the customer.

Easy remote provisioning

3CX Phone System can easily provision remote IP Phones and 3CXPhone instances via the extended SBC which acts as an agent for provisioning requests. With the Session Border Controller you can send phones readily configured for true plug and play at the customer site.

Eliminate firewall and bandwidth issues with inbuilt Session Border Controller

3CX Phone System features the unique SBC, which allows all SIP traffic for the customer to be tunneled over a single port. Drastically simplify remote installs and eliminate firewall configuration issues. Furthermore, the intelligent 3CX SBC can detect calls being made between local extensions and avoid sending audio streams to the Virtual PBX – saving valuable bandwidth and dramatically improving audio quality.

Licensing

Each 3CX Virtual PBX is licensed separately, depending on the requirements of the customer, i.e. number of simultaneous calls, whether customer requires PRO edition and so on. The actual platform - i.e. the installation of 25 instances, is provided FREE of charge. Licenses for 3CX Phone System are available in two types:

Perpetual licenses

Customers can buy a perpetual 3CX Phone System license that can be activated either in the cloud or on-premise. This is the most economical way to license 3CX Phone System.

Subscription licenses

Customers that prefer to pay per month or per year, can opt for time based subscription licenses. Time based licenses include maintenance but are more expensive in the long run. However they allow partners to license 3CX Phone System for short period of times and reduce the ‘risk’ when entering into contracts with customers.
