Re: ipException with jain-sip-presence proxy: Could not forward request

Linonel,

Can you try upgrading to the latest jain-sip jar. You can get it either 
from the NIST CVS repository or you can try the tar.gz posted to the 
documents and files section of the JAIN-SIP project.

After you do that, if you are willing to work with me to resolve issues, 
we can get the proxy updated. Its been long ( too long) on my todo list 
as I am pushing to get JAIN-SIP 1.2 completed.

Thanks and regards,


Ranga
