softphone(redirected from soft radio)
softphone(SOFTware PHONE) An application for making phone calls via computer over the Internet. Known as "voice over IP" (VoIP), either a headset or a microphone and speakers are required. Softphone functionality is also available on smartphones via Wi-Fi rather than the cellular service (see Wi-Fi calling).
Softphones can work stand-alone or be part of an IP PBX family. They offer the full range of phone features, such as call forwarding and conference calling and may also interface with applications such as Outlook for automatic phone dialing. See VoIP, IP phone, IP PBX and IP telephony.
