did anyone implement SIP on J2ME before, I did it, but it running pretty slow. receiving response from server is really slow so that I cannot test my streaming part. Because I use SIP and RTP at the same time. In fact, RTP is after SIP.
Another one, how to install Jad or Jar file on S60 SDK. I did not use it before. I am newer to S60 SDK environment. I usually use J2ME Wireless Tookit.
