The Vopium application will use the 3G feature of iPhone to enable VoIP calls to other VoIP enabled devices. More importantly, if the iPhone is Wi-Fi enabled then Vopium will help make free calls to other users on Skype, Gtalk and Vopium. A great step forward is the approval that Vopium has received from iPhone. One can now download Vopium directly from the iPhone store itself making its availability very ease. Another advantage of this application that brings VoIP to iPhone is the enabling of messenger services or IM environment on iPhone using which one can now connect to msn, Skype, yahoo, Gtalk and twitter, a social networking site making communication and socializing even more easy.

This technological breakthrough also comes with a fair set of promotional offers. One of them is that if you take the Vopium application from the iPhone store right now, you will get up to 30 free SMS and free calls worth 30 minutes. You must ensure that the automatic setting of 3G VoIP calls is disabled in your phone and you can start at your will by connecting in 3 ways including  3G, Wi-Fi or the normal mode.

VoIP call is very much vulnerable to attack. Hackers can readily get into your communication link and the conversation with your friends or clients remains no longer private. Companies offering VoIP service should keep this point in mind that how much secure is their service. In order to prevent hacking and make the conversation much more secure, VoIP service providers much opt for several layers of security system which can be achieved by breaking or dividing the network in several secure zones and then adding firewalls or other security measures to each of them. Special encryption method should be used which should be kept highly confidential.

Internal traffic flowing is another fault which the company usually forget about. When more number of workers start using VoIP communication on a single channel, then security issues really face a serious threat due to this huge traffic. So like your PC which you keep protected using an anti-virus system, similar measures have to be applied for VoIP telephony too as it is not of server but of network’s concern.
