call.center, an innovative SIP-based softphone that can be used on Macs, Windows, iOS, and Android tablets, is for those who want full control over their business communications. Note that call.center can be used as a standalone softphone, and not as a VoIP service. To make or receive calls, you will need a subscription to a SIP-based VoIP provider or a SIP server.
Note: Sometimes network operators may restrict or prohibit VoIP functionality. They may also impose additional fees and other charges for VoIP. You agree to comply with your carrier's network restrictions. DIDWW is not responsible for any fees, charges, or liability imposed on you by your carrier for VoIP over mobile/cellular data.
