Review Date: Saturday 6/17/2006 1:38 PM CST
Review Deadline: 7/01/2006
Status: WGLC 
Section: 2.4, 2.5 and 2.6 related to Transfer

Summary: 

2.4.  Transfer - Unattended
------------------------------

1) The "Supported: replaces" message-header line in F1, F3, F4, F11 and F13
   is superfluous and I suggest to remove it

2) The session identifier (2890844527) is the same for Bob's SDP offer in F1,
   and for (unrelated) Carol's SDP answer in F13. 
   idem for the audio transport port (3456)

3) IP addresses appear to be:
   - 192.0.2.105 for Alice
   - 192.0.2.113 for Bob

   As a result, in F6: (response to Alice)
       ;received=192.0.2.113
   is to be replaced by:
       ;received=192.0.2.105

4) In F5, the initial value of the sequence number for this first request on the UAS
   side within this dialog is very unlikely to be 2.
   Although it is not incorrect in the strict sense, I suggest the value 101 for
   avoiding any confusion.

   Therefore, the line:
      CSeq: 2 REFER
   is to be replaced by:
      CSeq: 101 REFER

   and as a result:

   in F6, the line:
      CSeq: 2 REFER
   is to be replaced by:
      CSeq: 101 REFER

   in F9, the line:
      CSeq: 3 BYE
   is to be replaced by:
      CSeq: 102 BYE

   in F10, the line:
      CSeq: 3 BYE
   is to be replaced by:
      CSeq: 102 BYE


2.5.  Transfer - Attended
-------------------------

1) In the comments before the message details, the line:
   prepared, if the triggered INVITE had fails, to retry the REFER with
is to be replaced by:
   prepared, if the triggered INVITE had failed, to retry the REFER with

 
2) IP addresses appear to be:
   - 192.0.2.103 for Alice
   - 192.0.2.113 for Bob
   - 192.0.2.123 for Carol
   As a result:

   in F20: (response to Alice)
       ;received=192.0.2.123
   is to be replaced by:
       ;received=192.0.2.103

   in F23: (response to Carol)
       ;received=192.0.2.103
   is to be replaced by:
       ;received=192.0.2.123

   in F24: (F20 response to Alice in the message/sipfrag body)
       ;received=192.0.2.123
   is to be replaced by:
       ;received=192.0.2.103

3) F19 has 2 extra whitespace lines


2.6.  Transfer - Instant Messaging
----------------------------------

1) In the text/html body of F5, the to-tag should be: 3145678
   as a result, the line:
       12345600@atlanta.example.com%3Bto-tag%3D314159
   is to be replaced by:
       12345600@atlanta.example.com%3Bto-tag%3D3145678

2) In F7, F8 and F9:
      Call-ID: 563456212@b2.biloxi.example.com
   is to be replaced by:
      Call-ID: 563456212@b2.chicago.example.com
