RFC3398, "ISDN User Part (ISUP) to SIP Mapping"
Source of RFC: sipping (rai)

Errata ID: 2580

Status: Reported
Type: Technical

Reported By: Stephen James
Date Reported: 2010-10-19

Section 8.1.3 says:

Item 6.
The gateway also sends a CANCEL message to the SIP node to
terminate any initiation attempts.

It should say:

Drop this statement.

Notes:

No CANCEL is sent on INVITE transaction timeout. This is per 3261 "If
no provisional response has been received, the CANCEL request MUST NOT
be sent; rather, the client MUST wait for the arrival of a provisional
response before sending the request."
----------------------------------------------------------------------
Recommended status:  (correct) Hold for document update

Section 8.1.3 item 6 should be updated to "The gateway also sends a
CANCEL message to the SIP node to terminate the initiation attempt if
a provisional response has been received."  The situation illustrated
in section 8.1.3 does not distinguish the "provisional response
received" case from the "provisional response not received" case, so
the commentary should cover both cases.  (The specific example
diagrammed shows the "no provisional response received" case.)

A similar change should be made to section 8.1.4 item 7, "The REL will
trigger a CANCEL request to the SIP node if a provisional response has
been received."

A similar change should be made to section 8.1.7 item 7, "Upon receipt
of a REL message before an INVITE final response, the gateway will
send a CANCEL towards the SIP node if a provisional response has been
received.

Since a reader familiar with SIP will know the rules for sending
CANCEL, this correction is not crucial for proper implementation of
the RFC, so I am recommending that it be held for document update.

Section 5.1 - 5.3 says:

Notes:

Sections 5.1 through 5.3 use unexpected irregular, non-uniform
indentation in hanging lists; this is accompanied by dangling
hyphens in 5.2 ( s/third- party/third-party/ and
s/crypto- agility/crypto-agility/ !).

[[ second-to-last paragraph, on mid-page 24: ]]

   Related to SRTP's characteristics is a goal that any SRTP keying

It should say:

Rationale: language/grammar improvement -- keep for update!
