Why Voifone is your best choice for International calling, IM, file transfer and video calls

Voifone Account

Your Voifone account resides on our server and provides your account details such as your profile, call detail records, password management and the ability to add funds.  Your account on our server drives the features delivered by your softphone.  We’re an ITSP (Internet Telephone Service Provider).  To understand the relationship between our company and the software residing on your cell phone or computer, think of us the same way you view cell phone carriers.  The carrier provides the phone service and makes the features of your cell phone work.  Your cell phone is made by an independent manufacturer and is the device through which the features you want, are delivered.  Here are two screenshots providing a sample of what you’ll see when you log into your account:

What’s a Softphone?

Softphones are software applications that provide the services of a telephone and usually much more!  They’re also known as “SIP” (“Session Initiated Protocol”) phones.  If you do a quick Internet search, you’ll find plenty of softphones, most of them are free, or have free versions.  Many have a combination of free and paid versions.

Most softphones will work just fine with your Voifone account so feel free to experiment and use the one(s) you want.  We do have our favorite softphone and have optimized your account to provide all its features.  It’s “Linphone” from Belletone Communications (a French company).  If you install Linphone and connect it to your account, it’ll look something like these screenshots, depending on whether you’re using it on a desktop computer or a mobile device:
