Using normal telephone network (PSTN Network)

VOIP calling cards are mean to be cheaper but with realtively low call quality compare to normal telephone network. As Call4U considers quality is the most important feature of our services, we are forwarding calls via normal telephone network. This means we will send calls using our digital phone line (ISDN line) using normal telephone network (PSTN network).
