So, maybe one of the VoIP experts that showed up on this thread can help me with one doubt... Let's say that I have a LDAP server where I manage user accounts, and I want people to be able to call each other with any SIP-enabled phone. I am not interested in voicemail/IVRs/any type of "voice application" on top of that. Do I really need Asterisk/FreeSWITCH or can I just go buy by setting up something like Kamailio?

Kamailio is what is called a Session Border Controller. Its primary purpose is to provide protection and some lightweight filtering for the media servers/PBXs behind it. Once you want "advanced" features like voicemail, parking, hunt groups, three-way calling, etc, you will need to use a PBX like FreeSWITCH (recommended) or Asterisk (not) behind it anyway. If you're only running a single machine, an SBC isn't really worth the trouble.

  > Once you want "advanced" features like voicemail, parking, hunt groups, three-way calling. Right, but what I am saying is that I don't want any of those features. At least not yet. I just want to give my customers a sip address (username@communick.com) where they can call other SIP addresses. In that case, is that a PBX still needed?

    You certainly can use Kamailio but it will be much easier/faster to get something going in Asterisk. You don't need to run any of the advanced features in Asterisk (and can completely unload the modules if you want).
