My partner and I started a company together and we both work out of our home. We did not want to spend a lot of money on a phone system. We did some research and we signed up for a virtual pbx service online. We configured the system in less then a half hour including getting our greetings recorded. The virtual pbx system helps us sound more professional and streamlined our communications. We have been using http://www.iTeleCenter.com for a few years and we have been very happy with the service.
