Soft Phone Support Voice and Video Calling Using Sip And Rtp Protocol
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 2
Abstract
Soft Phone is a VoIP soft phone that uses the Session Initiation Protocol. It is a powerful and unique SIP software telephone that lets users make phone and video calls using single software application using any Voice over IP (VoIP) telephony provider. As a fully featured SIP client, Soft Phone is designed from the ground up to work with current and future IP-based. Soft phone can be used in the place where we need establish the voice and video phone calls in the IP network. This can be installed at any personal computer. It uses the SIP protocol to establish the IP session and using RTP, RTCP and RTSP for media transmission. Using Soft phone they make call to any Soft Phone and Physical hardware SIP phone which can understand the SIP protocol.In computing, a soft phone is a software program for making telephone calls over the Internet using a general purpose computer, rather than using dedicated hardware. A soft phone is usually used with a headset connected to the sound card of the PC. To communicate, both end-points must have the same communication protocol and at least one common audio code. Many service providers use the Session Initiation Protocol (SIP) standardized by the Internet Engineering Task Force (IETF)
