[sip-comm] initialize media descriptions problem...


#1

Hi all,
Thanks for your immediate answer before. Now, I can run sip-communicator successfully!
But, when I wanted to connect with others , a problem happened....

net.java.sip.communicator.media.MediaException: Apparently all media descriptions failed to initialise!
SIP COMMUNICATOR won't be able to open a media stream!

What should I do to initialize media descriptions?
( I have already installed JMF. )

Please help me.
Thanks to all of you.
