Customer Buzz

"This is working out great for me for when I work from home I don't have long distance on my land line and I don't have a limited cell phone plan. I work in a call center so I need to be able to call my customers, which are located all over the country. I forward my office phone to my CoSo TeamUP number and I can pick up the calls from my office computer or from my home computer."
