    Re: J2ME incoming call port

    Hmmm... I'm not sure how to answer your question satisfactorily. Essentially, you cannot listen to incoming calls, because there is no way to listen to incoming calls.

    When you say "listen", do you mean, access the audio data?

    You cannot do this quite specifically because it would allow you to violate the user's privacy. This is the same as there being "a default port for SMS"... you cannot intercept SMS that is received on the default port. The Java sandbox concept exists to protect the user from applications that could be harmful or intrusive.

    Well Randika, I don't think call works on any port. Even in Symbian I am certain you don't capture call on basis of port, Its totally a different channel and protocol. Well there is JSR 253 for handling call but till now its not been implemented on any phone.

    Go to this link. there u can download specification and javadoc for JSR 253
    au revoir
