Hosted business phone system is an ideal solution for business now. You don't have to worry about installing any software or hardware. However, can have access to all the features large business have. The best part is the price is very affordable. It starts from about $19.50/month. You will sound as professional as fortune 500 companies. I have been using PBX from Telcan. I believe they provide PBX at the best price. They even gurantee to beat any lower price by 10%. http://www.telcan.net
