Virtual PBX is a word, which is often used together with Hosted PBX, but there is a slight difference: virtual PBX may refer to a very basic and simple system that handles only calls in limited locations. You can view the Virtual PBX as a low cost version of the Hosted PBX. The main difference between Hosted PBX and a Virtual PBX is that the latter one handles only in-bound calls. This can be an ideal solution if you own a small business, where less than 10 people work and do not use much telephone traffic.
Of course having the physical PBX system at your office gives you more control over communication system. For example, if you need to add or delete a line from the system, no need to contact the provider, but all can be done within the company by its IT staff. People doing it must have good level of competency to do that configurations. Hosted PBX frees you from the need to have an IT staff competent in VoIP, but then your control over the system is limited.
Voicebuy is proud to offer its loyal customers an exclusive chance to establish their private communications system. All registered Voicebuy users receive a possibility to have their absolutely Free Hosted PBX system and connect their offices or representatives in different countries. There are many companies, which also offer free virtual PBX systems. Though not having all features of Hosted PBX systems, virtual PBX will give you such features as Voicemail, Auto attendant, Unlimited call handling (no busy signals), call forwarding. Some limitations of the virtual PBX include handling of in-bound calls, extension numbers are limited, no Fax over IT, only a set amount of free minutes, conference calling may be charged.
So ideally you would opt for a hosted PBX system, but if there are budget considerations, a virtual PBX may offer you the very set of features, which will let your small business have necessary VoIP communications systems set and ready.
