COMpact 5500R

A purebred IP performer – and yet offering multiple options!


80 IP channels in a compact housing: feel free to upgrade your COMpact 5500R to the desired size!

No matter whether you're a promising new start-up or an established company that's planning to expand - this VoIP appliance can help keep all your options open. The brand new COMpact 5500R has the ability to cope with increasing demands built into its DNA. Thanks to its fully modular architecture, even its base configuration, designed for up to 12 VoIP subscribers, can also handle up to 112 subscribers (including remote extensions) and also provide all the functions of a "large“ IP server.

When it comes to “traditional telecommunication” this system makes life really easy: Analogue and ISDN subscriber ports can be retrofitted as integrated gateways, for example, for existing telephones. The specially designed templates make setting up the VoIP trunks for all the major providers as easy as child's play. Even the "traditional" FXO and BRI connection types can be retrofitted using modules if required.

This compact system has excellent credentials when it comes to climate protection: Auerswald is the world's first manufacturer to have its ICT systems Blue Angel certified. This also covers the COMpact 5500R.

A VoIP appliance par excellence

Even setting up SIP trunks is child’s play: downloading a certain provider template right when you need it lets you always rest assured you’ve got the latest version. The retrofittable Ethernet port at the front of the housing is a special feature of the COMpact 5500R – ideal to intelligently separate telephony and data and perfect to embrace the new era of IP connections

Convincing as an overall system as well

Connected Auerswald IP telephones are also well catered for: thanks to provisioning, the initial setup is done almost automatically. Everything else can be centrally configured in a flash – with the new COMfortel IP Editor.



Bring efficiency and convenience to practically any environment with up to 50 workplaces


Agencies and freelance professionals

An online agency without IP telephony? No way!

After winning a new budget, advertising agency owner Marco F. has to expand his staff from 18 to 30 employees practically overnight: “Handling this account requires sufficient external lines which must function dependably even when there are many simultaneous calls”, he says. Since there are no separate phone lines in the new business premises, he opted for an IP-based system which also manages to integrate the mobile handsets of the IT crew and to show the IP cameras’ pictures on the receptionist’s phone display. Even though “the brain” of the system, the COMpact 5500R, will only be installed shortly before moving in, the whole team is looking forward to enjoying optimum work conditions.

1 Depending on the setup level of the system

We call it “fully modular”. This means: your needs are crucial.

Can you say what your needs will look like in the future? This compact communication server for up to 32 workplaces lets you remain on the safe side thanks to its full modularity: You won’t have to buy a new system if you want to convert to a different telephone connection, and should your company grow, expanding the system to comply with any new requirements is easily done. Either by activating access via our own “Online Upgrade Center” or by purchasing an appropriate module. The COMpact 5200R symbolizes versatility – here’s a small choice of the many options you have.
