The Unify X3 is the smallest of the OpenScape Business family suitable for rack mounting, but don't under-estimate its impressive power.

OSBiz X3

The HiPath 3000 range was the work horse of the Siemens telephony range with thousands of units and tens of thousands of users.  The move from HiPath 3000 to OpenScape X3 brought the applications from the enterprise OpenScape range to the reliability of the HiPath range.  We have maintained these products for over twenty years and can help you at every stage from specifying the right system for your business through to maintenance into the future.

Technical Details

The X3 system combines Unify's 30 years of telephone experience with cutting edge benefits and smart phone and desktop integration.  Aimed at smalll companies, it will grow beyond what most small busninesses will ever need. You may start with four handsets in a single office and this will be the perfect system for you.  Years later when you have over 100 people in your office, remote workers and field sales people, this system will have kept up with you.  You will have added some hardware, but the original system itself will be the same. 


Out of the box the X3 is equiped as follows (and can be expanded to these maximums*)

  • 2 ISDN2 Lines (expandable to 10 lines(20 channels))
  • 60 SIP (VoIP) trunks
  • 8 Digital extensions (expandable to 24)
  • 150 IP clients (expandable to 500)
  • 32 DECT handsets via up to 7 external DECT bases
  • 4 Analogue extensions (expandable to 20 for rack mount or 36 wall mount)
  • UC Smart client software (up to 50 users out of the box, expandable to 150 and then 500) 
  • The system comes rack mountable or wall mountable

OpenScape Business X3


The flexibility of the X3 is especially obvious in mixed infrastructures where VoIP is installed but traditional analogue and digital telephones, fax machines, and modems are still in use. The X3 supports any combination of IP, analogue, and digital telephones, as well as PC clients and cordless phones.

As a modular communication platform, Unify X3 is able to satisfy the requirements of companies with stringent demands. It is a flexible and scalable solution that can be combined with an incredibly broad range of applications and features and coordinated with the individual requirements of your company.


Unify X3 is an innovative and flexible convergence platform that perfectly adapts communications to your company structure. Whether your aim is to enhance growth or seamlessly integrate branch offices or mobile staff, the three expansion stages of the Unify X3 are the perfect solution for optimizing costs and business processes.

Enhanced features of traditional telephony combined with applications such as CTI (Computer Telephony Integration), UCD (Uniform Call Distribution), and Unified Messaging support all communications processes at the workplace and in all work environments. If an extension is left unattended, the Team function or integrated voicemail ensures that no call is missed.

And Unify X3’s user-friendly executive/secretary function ensures the smooth flow of communication at attendant or secretary stations in the reception area where multiple communications processes converge. Integrated call distribution ensures reachability and guarantees fast customer contact. All these factors combine to make telephony not only easier to use, but also more efficient.

VoIP (Internet telephony)

Nowadays, there are more network providers offering telephony services than ever before. As the de-facto standard for Internet telephony, induces Internet telephony service providers (ITSP) to provide attractive applications and business models.

With its SIP interfaces, Unify X3 helps to converge network services and to drastically cut communication costs. Unify X3 already supports new SIP options, including SIP phones or user and system connections for Internet telephony.

With Virtual Private Networks (VPN) and authentication applications, you can shape your company securely for the future with Unify X3, without any compromises in terms of security.

Lower costs

Consolidating voice and data communication in an IP-based network not only enables the deployment of applications that decrease company call charges and hardware costs, it may also increase productivity. A separate voice network no longer needs to be installed and maintained, resulting in decreased outlay for administration and maintenance for systems and applications, as these tasks are now centralized. In addition, existing Internet connections can be optimized for calls to the public telephone network, thereby reducing the costs for separate ISDN lines.

Flexible configuration

The “One wire to the desk” concept allows additional telephones to be connected via an existing LAN cable. Integrated miniswitches are used for connecting the PC. Power over Ethernet switches supply power to IP telephones without the need for additional PSUs. Convergent platforms allow DSL and ISDN connections to be combined. ISDN connections can be configured as backups in case a fault occurs in the IP connection to the provider. They can also be configured as additional channels, for example, for fax machines or modems
