    Re: how to implement VOIP using sip in j2me

    I'm not into j2me, but even though there's a jsr for sip (see JAIN) currently there's no way to handle audio stream on it. So other than signalling, you won't be able to do much..
    Besides, latency would be quite an obstacle too.. so you'd better get your hands into c++ if you want to achieve this.

    Re: how to implement VOIP using sip in j2me

    Ok,I knew it.
    Today,after many days hard working ,We do make a little progress.
    First,We almost knew how to get/record the voice come from MIC.and how to play it (By the MMapi's help).
    Second ,we still got a big problem in "when I already got SIP connection with another Proxy,how to transfer data by RTP",We don't have any information (api,open-source,etc.)

    Did anybody can give me a hand?
    thanks

    Hi jarodd,

    Do you use J2ME for your project or C++? Can you share with us some ideas? I'm also planning to make a VoIP client on N73 using J2ME.

    Thanks,
    Marc
