Elastix is great, it's responsive and so far, works like a charm, its obviously a great tool! But (sorry!) I need to turn some things off for a while while I get up to speed on the basics and get more RAM. I'm using 87% of my system memory at idle without any calls or messages. That makes me worry about stability under load. I want to keep the core PBX, asterisk, fax. In the interest of stability in only 256MB of RAM I want to disable, reversibly, the email, a2Billing, IM and CRM functionality just for now. Is there an obvious place to do this that I am overlooking? Sometimes I overlook things that are just staring me in the face. Thank you!
