You can’t afford to miss a call, but you also can’t stay tethered to your office phone all the time. Virtual PBX is one possible solution. my1voice uses your existing phone equipment, and can connect calls to any phone, whether or not it’s in the office.  Operations are handled over the Web. So small offices can look bigger without investing in pricey PBX system hardware. You still have to pay for your phone lines, and extra minutes can be pricey (the cheapest option is $10/month, with 100 free minutes; 5 cents/minute after that). 30-day free trial; 24x7 customer service.
