1. Porting of Bluetooth Stack:
This stack includes RFCOMM, L2CAP and SDP protocols. PPP over Bluetooth and LAP (LAN Access Point Profile) is being ported to have access to the network by using Bluetooth link.
2. Porting of H323 components:
H323 is a de-facto standard in VoIP domain. It has four basic components End Terminal, Gatekeeper, Multipoint Control Unit and Gateway. By making use of End Terminal, User can set up a call and make voice communication over IP networks. Effectively, this is a component that resides in the hand of user in any of the form that may be IP telephone, laptop, PDA or even any other similar kind of possible device. Porting of this component on T-Engine platform would expand the horizons of H323. Also, Gatekeeper is the component whose prime jobs are address translation, security, bandwidth management and admission control. It is being ported on T-Engine ARM based platform.
3. Integration of Bluetooth with H323 over T-Engine:
End Terminal of H323 uses TCP and UDP over IP for call set up and actual voice data transfer. For real time data transmission, it uses RTP/RTCP over UDP. In order to transmit voice data using Bluetooth ACL (Asynchronous Connectionless Link) instead of SCO (Synchronous Connection Oriented link), End Terminal of H323 would be mounted over Bluetooth to achieve Voice Over Bluetooth that would be effectively implemented using RTP/RTCP over UDP; UDP, TCP/IP over PPP and PPP over RFCOMM of Bluetooth stack.
