Since a FreeDID is basically a local phone number, they can be used the same way. Here are some examples:
• Receiving wi-fi phone calls - by simply downloading one of many free SIP/VoIP phone applications onto your smartphone, you can use our FreeDID to receive phone calls without using your mobile provider's network. Rather, calls are routed to your phone over your high-speed internet connection.
• Making wi-fi phone calls - since each FreeDID comes with 60 minutes of free domestic outbound calls, you can also make calls using the same free SIP/VoIP phone application.
• VoIP enabled PBXs (IP PBXs) - since our FreeDIDs are delivered using SIP trunking technology, you can easily connect them to any SIP enabled PBX such as Asterisk, 3CX, Trixbox, Elastix and more.
• A second phone line for your smartphone - many of our users use our FreeDIDs as a secondary phone number. This allows them to advertise a different phone number than their personal cell phone number when the need calls for it.
