RFC 3665, "Session Initiation Protocol (SIP) Basic Call Flow Examples", December 2003

Source of RFC: sipping (rai)

Errata ID: 5294
Status: Reported
Type: Technical
Publication Format(s) : TEXT

Reported By: Yehoshua Gev

Section 3.1 says:

BYE sip:alice@client.atlanta.example.com SIP/2.0

It should say:

BYE sip:alice@client.atlanta.example.com;transport=tcp SIP/2.0


In Example 3.1, the URI of the Contact header field of the INVITE request (F1) containes a parameter "transport=tcp".
According to section 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:

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