Re: Client does not send ACK for 200

Hi, I find out the problem, maybe it is useful for anybody who use
eyebeam as client.It is nothing to do with JAIN Stack.

The reason in 200's contact header a domain is used "test-ims.org"
instead of ip address. Eyebeam resolve the contact header ip address,
the DNS server can not resolve it so eyebeam does not send a ACK. Other
client does not care the contact header at the momment and send ACK.
