telecommunication system with linux support/community

Hi all,
I am searching for a new telecommunication system (i don't know, if this is the correct term for: a system for a company, that supports a telephone for every employee, sharing incoming calls between them and so on).
These systems often come with windows drivers that support dialing with ms outlook. Does anyone know such a telephone system, that comes with linux support? Or a system with independent linux community?
Thanks a lot,
Clemente

Perhaps Asterisk fits the bill?

Hi Hangdog,
asterisk is a software solution and would be nice. But I am searching for a hardware box.
Hardware telecommunication central, linux workstations (and servers). And I wonder, if the benefits, telephone system manufacturers grant to windows users, are for us, too...

Hi Clemente!

We have an VoIP Apliance (Hardware) with any kind of BRI, PRI (ISDN) or Analog Cards...

Just tell us how many lines do you want to integrate, and we will return prices as fast we can get...
