Hi all,
I am looking for some documents describing call flow of VCS-E and VCS-C in H.323 just like the jpg I attached.
(Especially when an endpoint dials from internet to intranet)
Is there any documents like tthat?

Call flow while VCS-E use ASSENT for traversal protocol (pretty much same even use H.460.18 for signal flow).
Please note this call flow include only key messages not every message exchange between Endpoint & VCS as well as VCS-E & VCS-C.

Hi!
I do not have something out of the box, but you should be able to make it yourself.
The debug capability on the vcs can help you here, as well as analyzing a network trace with wireshark.
It will have a lot of similarities of your drawaing, besides possible assent/h460.18 and different media flows.
Why do you ask?

Hi Taniguchi-san,
Thank you for your information.
This is exactly what I wanted.
BTH this call flow seems to be one page of a document.
Where can I get the document?

This is something I created in ppt format for signal reference and not published as official document.
