Telesphere is always quick to assist with any issues. I know that every carrier isn't going to be perfect and have the most reliable services, or have 100% up time. It's all about how the company you have services through handles the issues. I can tell you from personal experience even through I don't have many "issues" with Telesphere that always go above and beyond to take care of what ever. For the reason alone, I give them 4 stars and recommend them to anyone looking for hosted services.
