Hi I've been using PIAF for several years on the same server. I've been changing hardware recently and started with Ubuntu Server 14.04 on its own server. This runs postfix, web, and a couple of other applications. This server has plenty of ram, storage, and processing power. Is this a candidate for piaf or incred? Do I need virtualbox? I'm running 6 trunks and 8 extensions with moderate call volume. There is limited IVR and Fax. Thanks for your response.
