    SIP/RTP session

    someone can answer me:
    - Is it essential to use SIP to send data in real time by RTP (mobile to mobile)?

    At least easier to use built in SIP profile.

    If you need to send data peer-to-peer than the answer is yes. This protocol is used in the IP-telephony. But there is another solution - multicasting. But that depends on your needs.

    In other words SIP if you need 'Sessioning'.

    Re: SIP/RTP session

    thank you for the reply,
    in fact, I want to send a few seconds of video from mobile to mobile in real time. I found that the only way to make a connection M2M:
    1 - CSD -> ignored for this case, CSD does not
    2 - RTP for the transport and SIP for managing sessions
    other solution?

    Re: SIP/RTP session

    what is your target?
    pushing data to another terminal?
    csd is not available for S60 3rd and later devices.
    using SIP/RTP could be a good choice.
    however,you need to design how to initialize communication(not SIP initializing) .
