The modern business professional knows the benefits of having access to a mobile phone while on the road or working away from the office, but many of them have never had to worry about cost-per-minute billing, roaming charges or International calling fees. The business unit, however, is more familiar with highly gauged expenses associated with providing employees with business cell phones. Mobile voice over IP offers a practical solution to cellular phone charges, without the need for costly initial investments.

Mobile voice over IP, or simply mVoIP gives the option of using a mobile phone to make or receive voice over IP calls; many even allow access to email and faxing capabilities, further enhancing the VoIP business communication experience. The basic requirement of mVoIP is to convert analog voice data to digitally encrypted packets that can be carried along a traditional VoIP network. On a traditional VoIP platform, this would be achieved with the use of a specialized ATA adapter, since the premise of mobile VoIP is complete mobility, an ATA adapter would be of no use since it requires the phone to be connected to a computer.

Previously, a shortage of data capable mobile phones coupled with a minute availability of reliable networks made is difficult to utilize VoIP on a mobile front. Modern technological advancements and greater superiority in technical design have resulted in the majority of modern mobile phones being intelligent enough to be able to utilize a VoIP network.

The prime motivation for most businesses to implement mVoIP is the ability to mobilize employees, allowing them to remain connected with business communications without having to be stationed at their computers. Mobile VoIP allows for any mobile phone to essentially be used as a main business phone, without having to budget for costly mobile expenses. For professionals who must take frequent long distance business trips, mVoIP helps to eliminate costly roaming charges and provides unlimited long distance calling options.

The only hardware required to reap the benefits of mobile VoIP is access to a wireless network, or WiFi hotspot, and a SIP enable mobile phone. Alternatively the majority of smart phones with active data plans are able to support mVoIP functionality.
