Session Initiation Protocol
Session Initiation Protocol (SIP) is a protocol developed by IETF MMUSIC Working Group and proposed standard for initiating, modifying, and terminating an interactive user session that involves multimedia elements such as video, voice, instant messaging, online games, and virtual reality.
SIP clients traditionally use TCP and UDP port 5060 to connect to SIP servers and other SIP endpoints. SIP is primarily used in setting up and tearing down voice or video calls. However, it can be used in any application where ses ....etc

Internet Protocol (IP) Telephony has many issues that have to be overcome before it can be considered a rival to the existing telephony infrastructure. One such issue is the quality of service. The use of play-out buffering at the receiver helps to improve the quality of Voice over IP (VoIP). A buffering algorithm has been proposed by Narbutt, which uses a dynamic approach to buffering. This algorithm is adjusted automatically according to an estimate of the network delay. This is more suitable to the changing network conditions usually experi ....etc

Broadband and advancements in voice technologies are changing the way we used to communicate. Long distance telephone calls are made cheaper by services like skype and Jaxter. The same technology is affecting mobile services also. Most new phones have lots of memory and processing power. And with the data services on mobiles improving, its possible to place internet phone calls via mobiles.

J2me provides a SIP API specifically for this purpose. Using this API an application can be developed that can communicate with any SIP service and that ....etc

Mobile based sip-communicator ,real time application implemented using j2me and sip api,The Session Initiation Protocol (SIP) is a signaling protocol used for establishing and controlling multimedia communication sessions on networks that use the Internet Protocol (IP). A session is as simple as a two-way phone call. SIP was primarily designed to establish, modify, and terminate sessions, This simplicity makes SIP quite scalable and extensible, and it can be used easily in different architectures and deployment scenarios. SIP is already being u ....etc
