I have tried to deploy dimdim zimlet in
- zimbra network 5.0.16
- zimbra network 5.0.18
- zimbra network 6 RC1

without success, I have got the same problem

I have a dimdim server working on (on my LAN):
ht tp:// flux.mydomain.com/dimdim/

I have installed and deplyed the dimdim's zimlet without error in mailbox.log

I have put these values in the zimlet preference:

collaboration workspace url: ht tp://flux.mydomain.com/dimdim/
network profile: LAN

but I can't neither start nor join a meeting, I get this message:

room busy check failed! try again!

and I have no errors in mailbox.log

any idea???
