Samsung OfficeServ 7100

Samsung Telephone System

This system will provide up to 32 extensions.

This model gives you a good base to which you can add IP. This will allow you to grow the system to a reasonable size. The modules (extension, trunk and line modules) can be transferred into the bigger versions. And the 7200 can be transferred into the 7400.


  • The model’s chassis are different, but the handsets are the same. The handsets are interchangeable across the range (excluding the 7030).
  • The modules for the 7100, 7200 and 7400 are interchangeable.
  • Although it’s a basic system, it includes more advanced features like group mailbox.
  • Supports analogue, digital and IP.


  • As the system is modular, it can be quite pricy
    to deploy.
  • Space is less of an issue, but you end up with a
    big system as you have multiple modules.
  • Networking this system is quite complex.

Who is this system ideal for?

  • A business that is probably continuing to use
    traditional 2 wire phone connections or extensions.
  • A company that’s not too tech driven.
  • Industries like sheet metal work, metal
    manufacturing. Those traditional places that have big areas with one phone in
    the middle of a factory floor.
  • Most suited to a one site business.

    Frequently Asked Questions


    An analogue phone is just for voice services. To do other things, you have to dial a number or press a recall key to get transferred. It uses a basic phone handset that requires the system to provide power.


    A digital phone can provide call information, extension status, information from other extensions and calls. This is displayed on the handset e.g. Caller ID etc. This also requires the system to provide power.


    An IP phone uses a data network to communicate with the phone system. It is more like an IT device, a laptop, or a smart TV. It requires structured cabling so doesn’t work over traditional 2 wire telephone cabling. An IP phone also requires a network switch to provide power to the phone itself.

    A soft phone is an application or a piece of software that is installed on your computer/phone/tablet that allows you to connect to a phone system over the mobile or data network. This is in place of a physical phone. You open the software/application and it displays a phone interface that you use as if it was a physical phone. 

    Software like Skype and WhatsApp are soft phone applications. It creates an audio or video connection. On software phones connected to phone systems, they also give the option to transfer to another extension, transfer to voicemail and other features. They work the same as a physical phone but with reduced functionality - as they don’t give you the same features but you can see who’s on the phone and listen to voicemail for example.

    Unified communications bring all the different ways that people communicate into one platform. They may have a physical phone on their desk, a mobile phone, emails and possibly social media.

    An example of this in action would be a call that comes in first to your desk phone, then to your desk phone and mobile, then it diverts to your voicemail which is then delivered to you as an email. That is then tracked by your CRM system. The unified communications system integrates with the other software.

    Computer Telephony Integration is a system or technology that allows a phone system and a computer to connect or integrate.

    These integrations allow advanced features to be used, for example caller information popping up on your screen (often known as call popping), advanced call transfer functionality, call routing, and call centre systems.

    Some larger or more advanced phone systems require a chassis which is like a rack or filing cabinet which contains 3 rows of slots.

    Each of those slots is the right size for a module to give you connectivity on the front to either connect your extensions or connect your lines or an application like voicemail.
