Target is to program a flash based VoIP (SIP) Phone / Server like goribbit.com. Please take a look at how it works. For the client side if a clone of their api they offer but using different servers and sip accounts.
Following are the requirements:
The client will need to be flash based which can work with the internet browser, it should support voicemail, audio recording, phone book and missed calls. Also should have some user functionality.
- Implementation of a server side framework to allow flash clients to place and receive phone calls in the browser. To PTSN or SIP phones.
sip ---> flash media server
flash media server ---> sip
flash media server ----> flash media server
- Server side application that is based / or connected on / with the Red5 Java Flash Media Server
- Codec must support G711 and G729 audio codec in real-time. So the RTMP stream from flash has to be converted to the RTP VoIP stream.
- It must supports audio and video calls with h.263 codec
- In addition to that the corresponding SIP signalling to a VoIP application server has to be established. Explanation: The VoIP protocol consists of a SIP signalling text based protocol which used port 5060, and a corresponding audio stream (RTP stream) that uses higher ports between 20000 - 40000
- The process also has to work the other way around. If an audio VoIP call is received on the our voip platform server it is send to the red5 server that has to convert the call to a flash media call.
- The implementation should be based on the following open source components: Red5 (Java Flash media server), Java SIP Protocol stack (e.g. Jain), Open Source RTP stacks for Java (just search for RTP/java in google)... or other
server side is to use the existing open source libraries, integrate them and make them work together.
Please bid only if you could fulfill the requirements and if you are experienced in VoIP.
The design is not important, but We need all source files of project.
