asterisk users - Jun 2014 - SugarAsterisk vs. ________

Is this completely open source?  And all it's dependencies?

Is it free as in free speech and free as in free beer?  I know there are 
a few variations of SugarCRM.  

We're currently using an Asterisk hosted PBX with Cisco hardphones.  
Conceivably, we could run something like SugarAsterisk on the local 
network, and it would connect with the remote Asterisk?

Inbound and outbound calls would be routed appropiately?  Of course, it 
requires the Asterisk manager to be enabled...

What are some alternatives?  We only need the "contact center"
software
for asterisk, not asterisk itself.  There's another variant (or perhaps 
the same thing) at:

lists a few options.  I'm looking for, literally, the simplest FOSS CRM 
for "click to dial" functionality, but don't know where to start.



thanks,
