    Undergraduate Project: VoIP Application - Help Reqd

    We have started off on our UG Project - To develop a VoIP application on the Symbian platform that could work (independently) on top of existing n/w connectivity such as GPRS/EDGE/UMTS. We have decided to use Symbian C++ for the same.

    We have identified the modules that we need to develop:
    SIP Stack over Symbian
    RTP implementation
    VoIP application using RTP and SIP

    We would be satisfied with a push to talk application in the end if we are unable to find a work-around the existing restrictions.

    1) Is a 2 month timeframe sufficient for this project?

    2) Could people who have worked on this before help us out with a clear idea of where we should start and how we should progress. It would be great if you could fwd sample source codes.

    3) Can we use the existing SIP stack plugin for S60 2nd Edition be used for the Symbian S60 3rd Edition FP1 as well? How do I test a sample call setup in the same??

    4) Can applications developed using the Carbide.C++ Express and Symbian S60 3rd Edition FP1 be ported directly to the Nokia 6600 phone?

    5) Do we have to worry abt the underlying connectivity i.e GPRS or EDGE or UMTS or WLAN in developing such an application? Can it be developed independent of this?

    Kindly help me out by mailing any attempts in this domain to kumareshp@gmail.com. Your help would be invaluable.

    Thanks!

    I'm also trying to do a project using RTP.
    To be honest you won't find many examples on RTP, it is not supported in the S60 SDK (I'm sure there must be some out there though). Probably your best bet (and what a lot of people will tell you) is to begin developing your own RTP code, as I am trying to do now, using the RFC as a guide.
    I don't know about the SIP related stuff though as thats not a part of what I'm doing, you might be able to use the existing code.

    Another option is to integrate into your application, I really don't see the need to rewrite the RTP code when its been done already. There are a number of open source implementation about. But I'm not sure if this can be done...so I guess I'm asking that now, does anyone know if it is possible?
