Auerswald COMmander Business Wired & Wireless ISDN access device

t's an extremely flexible system, which you can upgrade with analog, digital and door ports, to a total of 120 extension ports. For connections with the public telephone network, you can set up VoIP accounts and both ISDN basic rate interfaces and a PRI primary rate trunk line. And how is this for flexibility: COMmander Business lets you use either standard or system telephones, in IP, ISDN 2-wire (UP0) and ISDN 4-wire (S0) versions, thus fitting in with almost any existing infrastructure.
With the VoIP integration, you can make calls via the internet without even having to switch on your PC. Or external subscribers, e.g. your regional representative at the other end of the country, can be integrated into the infrastructure of the telephone system like an internal(!) subscriber. He can call from his office via the headquarters system and use all its cost-saving functions while his telephone number as indicated to his business partners is that of the headquarters.
You manage the system via its web interface. Different access levels allow users to configure their own features – not just from their local computer, but from any computer with internet access, using a web browser.
And if you're changing from a first-generation COMmander Basic or COMmander Basic.2, here's some more good news: you can use all existing card modules in COMmander Business!*
