RFC 3398, "Integrated Services Digital Network (ISDN) User Part (ISUP) to Session Initiation Protocol (SIP) Mapping", December 2002

Source of RFC: sipping (rai)

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.

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.

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."

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.

Section 7.2.4.1 says:

(+) If the cause location is 'user' than the 6xx code could be given 
rather than the 4xx code (i.e., 403 becomes 603)

It should say:

(+) If the cause location is 'user', then the 6xx code could be given 
rather than the 4xx code (i.e., 403 becomes 603)

Notes:

"Than" is used for comparisons. "Then" is used to denote something follows in sequence.
