Owned by tech giant J2 Global, eVoice is an excellent solution for small businesses and entrepreneurs looking for a virtual office telephone system. J2’s rapidly growing global network of more than 11 million subscribers testifies to the efficiency of the service, which includes everything from a 24/7 virtual receptionist to studio-recorded greetings.
The phone you use to record your greeting – and your surrounding – can turn your carefully scripted greeting into an unprofessional mess. Background noise is terribly distracting, so choose a quiet room or parked car to make your call. Landlines, or a “wi-fi enabled” cellphone call, can provide much better connection quality than a standard cellphone. If you must use a cell phone, be sure to use a high-quality headset for the best clarity.

Don’t forget Packet8 business services. They have a virtual PBX, with real extensions, the ability to have the system forward calls to your mobile phone and actual equipment (if you want/need it). We’ve been using them for the past three years successfully with employees all over the U.S.
VoIP phone solutions offer several tiered, scalable plans that are payable on a monthly basis.
