Cross Platform Groupware and PBXs

[Josh Pollak]

Sorry for the late reply, I appreciate the links.

I checked out the Scalix website, but it doesn't look like it supports 
calendaring on all platforms, and I'd rather go with a completely free 
solution, if possible.

About Open-Xchange, I didn't realize this SuSE/Novell technology had 
been release OS. I'll have to check it out, it and Citadel/UX look like 
the best two options.

Another question:

There was a bunch of chat about Asterix a few weeks ago... My company's 
reached 20+ employees on site, and we are sharing phone lines at the 
rate of about 1 line for each 2 people, which seems really silly. I'd 
like to get started setting up Asterix, where do I get started? I 
checked out the website, but not knowing much about PBX's its a bit 
intimidating. How do I go about hardware selection?

Would you recommend buying an asterix based commercial solution, rather 
than rolling our own? We'd like to save money, but we don't really want 
to have to worry about maintaining our PBX.
