Mobile VoIP is a high-speed phone service delivering voice communications over a conventional telephone network (or the Internet) through a cellular device. Mobile VoIP uses the same analog technologies that contribute to conventional voice communications over the public switched telephone network (PSTN). With mobile VoIP, the number of users can be increased without reducing the quality of the voice transmission over the public switched telephone network.

Mobile VoIP services are usually sold as a bundle or are sold as part of a 'virtual phone system'. A virtual phone system is a set of special-purpose hardware devices, including a computer with a microphone and speaker, a data port for connecting the computer to the network, speakers or headsets for making portable VoIP calls, a USB port for making portable VoIP calls, and an application program interface (API) that allow the software on the computer to communicate with the services provided by the mobile VoIP service. The API gives the client applications the ability to make their own modifications to the software or use a pre-written gateway application that will allow them to bypass the phone company's control and use their own unique port number for making calls. This 'one-stop shopping' solution makes it easy to incorporate mobile VoIP with other communication solutions.

Features of Mobile VoIP

With the advent of VoIP phones having an astounding variety of features, one can easily buy one that will fulfill all his or her communication needs. Most VoIP service providers offer several communication services at an affordable price. Some providers also offer free calling minutes after a certain limit is met. One can call international numbers for free, if one has a non-local number. Free local numbers can be obtained through local phone directories.

To take advantage of these amazing mobile services, one needs a compatible telephone model. An ideal choice would be one's current mobile phone, as the features and options are almost the same, except for the calling charges. One can also choose from a range of specialised and feature-rich smartphones that are specifically designed for making mobile VoIP calls. Once the correct mobile phone is selected, the user should enter the ten-digit Phone Number of the Mobile Telephone Number.

After the Phone Number has been entered, a mobile verification code is generated. Entering the phone number and verification code in a Web browser will provide a list of nearby mobile phone numbers. Click on the 'Show All Devices' button to display a list of all the devices. The user can then select one to call. The user can then choose to place a call, talk to the mobile by speaking into the microphone, or send text message to the mobile using the touchpad. The text message option can be useful when the person wants to send a message to someone who is not near him or her.

To begin using the Voice over Internet Protocol service, an account is created with an Internet Service Provider. Then, voiP software is downloaded onto the computer. An Internet connection is necessary for the software to function properly. An auto-attendant may also be provided. The auto-attendant will call the user automatically, even when the user is not using the handset.

Mobile VoIP has several benefits. Since the service uses the internet to call, one does not need any landline phones. Also, since the calls are made over the internet, one does not incur any extra costs. Free VoiP calls can be made within the USA and Canada, but international call rates are usually very high. In some cases, free calls are actually charged.

To get started, sign up for a mobile VoIP account. Once the account is opened, one can start making calls immediately. To avoid being charged for long distance calls, it is recommended that one opens an account from a local mobile phone service provider. This will enable one to have a local number and enable the call charges to be reduced.
