asterisk users - Jul 2007 - Creating an SIP softphone

Hello,

I have been reading up on the capabilities of the Asterisk-Java library.  I
believe that this library can act as an interface between a Java GUI(custom
softphone) and the Asterisk server.  Seems like the Live API would be easiest to
use to make the connection to the Asterisk server and to set-up calls.  One
thing I am not sure about is how to transmit the audio streams between
users' PC's once the calls are routed.  I can see that the Asterisk-Java
library can't be used for transmitting real-time audio(phone conversations).
Would anyone have an idea about how to complete the application I am trying to
make.  To be clear, I am creating a custom softphone, but can't find much
information on how to create the audio transmission.  Could anyone provide me
with some advice on how to complete this type of softphone.  I noticed that
there is a JAIN(SIP) API that can be used with java, but I would need more
information or examples on how this can be used for my application to use this
API.  I would prefer to use the SIP protocol, since it seems like its the most
common.

Thanks in advance,

Denis

JMF ( http://java.sun.com/products/java-media/jmf/ ) for audio... a good
example to use JAIN SIP and JMF is the SIP Communicator source code (
https://sip-communicator.dev.java.net/ ) ...

We've got a commercial IAX based java softphone SDK that might help you.
