The following errata report has been submitted for RFC3665,
"Session Initiation Protocol (SIP) Basic Call Flow Examples".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5294

--------------------------------------
Type: Technical
Reported by: Yehoshua Gev <yoshigev@xxxxxxxxx>

Section: 3.1

Original Text
-------------
BYE sip:alice@xxxxxxxxxxxxxxxxxxxxxxxxxx SIP/2.0

Corrected Text
--------------
BYE sip:alice@xxxxxxxxxxxxxxxxxxxxxxxxxx;transport=tcp SIP/2.0

Notes
-----
In Example 3.1, the URI of the Contact header field of the INVITE request (F1) containes a parameter "transport=tcp".
According to section 12.2.1.1 of RFC 3261, this URI should be used as the Request-URI for Bob sending requests within this dialog.
As there is no explicit text about omitting parameters from the URI, the Request-URI should contain the "transport=tcp" parameter.
Hence, the Request-URI of the BYE request (F5) should contain the parameter.

It seems that the this problem was reported some years ago in the sip-implementors list:
https://lists.cs.columbia.edu/pipermail/sip-implementors/2006-July/013507.html

The same problem appear in other examples, specifically 3.2 and 3.6.
