[SIPForum-discussion] I need urgent help!!!

[Bayram Kıran]

Hello,

My name is Bayram Kıran.I am from Turkey. I am attending Computer
Engineering

Department of Marmara University.
 I am a senior (4th grade) student. I have a final project this year. It is
to

implement a user agent that provides people
to talk and send instant messages by the means of SIP. Me and my project
partner

want to use jain-sip. Me and my project partner have downloaded the source
code of

a tutorial application from the site

http://www.oracle.com/technology/pub/articles/dev2arch/2007/10/introduction-jain-

sip.html.
We have achieved to create .jar file and execute it. But when one of us try
to send

a message to the other one, some error messages are thrown. The error
messages are

below:

ERROR - MESSAGE sip:bayram at 192.168.2.5:4001;
