Hi Xu Rui
Thanks for the flow
I did not understand why is the first re-INVITE towards A required
The media info got from the MS could be sent to A in the 200 OK itself
Whats your view ??
Thanks
Siva M

Hi Siva,
The sequence is broken by the mail client.
I put it in a text file as attachment.
There's no "re-INVITE" to C.
The "INVITE" to C is a new one.
PS:I think alex is right. :)
Regards,
Xu Rui

I think the announcement is played for A to be informed the call is
forwarded.

Hi,
I hope this sequence will be what you need.
But it looks something strange for me that B could listen to
announcement after it times out.
Hope it helpful.
