Siemens Hipath 3550 System


The Siemens Hipath 3550 system combines Voice over Internet Protocol (VoIP) technology with the utility of an in-house PBX or switchboard.

This modular system is centred around the wall mountable 3550 unit that receives all incoming calls and acts as the exchange to transfer calls to and between your separate office lines.

Key capabilities of the system:

  • Provides you with at least 44 phone extensions, and up to 156 depending on the combinations of phone line types you need.
  • Branch offices and remote workers can be integrated into the system
  • Configure your system in a way that suits your needs with ISDN2e, ISDN30e and analogue lines.
  • Your telephone and specific computer applications can interact through the CSTA interface.
  • The CTI Tapi Interface can be used by call centres to coordinate telephone and computer systems.
  • Remote maintenance capability for quicker troubleshooting.
  • Voicemail interface will work with both digital and analogue systems.

There are also some extra functions, which you can choose to add to your system:

  • Call centre function for up to 32 users, with call distribution and call data reporting
  • An automated attendant can answer your calls and play your customers a greeting message
  • Hold music or a message for callers

The hardware is supported by HiPath ComScendo software.

Siemens also offers a range of telephone handsets to use with the system.

What is the best way to buy one?


One option is to pick and choose which pieces of the system will suit your business best and buy them online.

This might be cheaper if you know what you need and have in-house technical support to set up and maintain your system.

Another option is to work with a telecommunications specialist company to design the setup that will work best for your business.

You can then buy and have the system installed directly by them.

They can provide options for just purchase and installation, or possibly offer an ongoing maintenance contract.


How does the Siemens Hipath 3550 compare to other options?


The Siemens Hipath 3550 is a great IP PBX option, as it straddles the middle ground between traditional internet-based telephone systems.

But you need to be sure that one of the other technologies wouldn’t suit your needs better:
