[reSIProcate] INVITE and re-INVITE without SDP, how can I share the improves ?

[Micky Kaufmann]

Hi,

I looked at all dum*.dot files - I'm working one of the latest svn checkedout version and it looks like there are many small bugs in the dot files (for example there are two states 'Finish' and 'Finished' that look exactly the same). I'm working on fixing these files and also on creating visio diagrams for them (soon I'll send them)...

Is there a newer version of those files?

Rodrigo,
Did you change the state machine for allowing the INVITE and re-INVITE without SDP transmission? (Did you use 'transition' function or any InviteSession state/event?)
Can you send a small description of the changes you made?
Did you change only the ClientInviteSession constructor or anything else?
Are you sure that the problem occurred only when you didn't send initial SDP?

Anyone else encountered that problem and fixed it?

Thanks,

Micky

Great!

I think a discussion of your new Invite session state transitions would be a good place to start.  Posting a modified dum\doc\dum-invite-connected-state.dot and dum-clientinvite-state.dot file would probably be the best way.  Also a brief description of the modified/added interfaces would be good. 

Thanks,

Scott

Hello,

I have done some improves to DUM to allow the INVITE and re-INVITE without SDP transmission.

How can I share them with you ? 

Best regards
Rodrigo
