        Technical Summary:

This document defines a new SIP URI parameter, 'iotl', which can be used 
in a SIP URI to indicate that the entity associated with the address, or 
an entity responsible for the host part of the address, represents the 
end of a specific traffic leg (or multiple traffic legs).


        Working Group Summary:

The document was considered in the DISPATCH WG. It was agreed to scope 
the document to 3GPP environments, and due to that publish the document 
as AD sponsored.

In response to IETF LC feedback from Robert Sparks, the scoping language 
was adjusted to clarify that the only current usage of this parameter is in 3GPP
networks, but it is also possible to use it in other deployments where its semantics
make sense.  The text change was discussed and agreed on the DISPATCH
mailing list.


         Document Quality

The document has been adopted by 3GPP, and a number of vendors within the 
3GPP community have indicated plans to implement the specification.
