Errata ID: 2161
Status: Held for Document Update
Type: Editorial
Publication Format(s) : TEXT
Reported By: Andrew Miller

Section 8.2.6.1 says:

504 Version Not Supported            127 Interworking (+)

It should say:

505 Version Not Supported            127 Interworking (+)

Notes:

504 appears twice with different text. From the context, it looks like the text in the second entry is correct, and the number is wrong.
