Subject: [Sipping] Nits on draft-tschofenig-sipping-captcha-00.txt

Hi,

two nits on the following draft:

http://www.ietf.org/internet-drafts/draft-tschofenig-sipping-captcha-00.txt

1) section 3.2 could show the ACKs of the first INVITE transaction.

2) An INVITE is typically called a re-INVITE if it is sent within an 
existing dialog. Since the INVITEs in the figures are not sent within an 
existing dialog (the 4xx response did not create one), they are not 
re-INVITEs but regular INVITEs.

Cheers,

Gonzalo
