Message sequence
TR/87(4) is an ECMA Technical Report that describes the use of SIP as
a transport of service requests and events defined by the ECMA-269(5)
specification as XML bodies within SIP messages. The ECMA-323(6)
specification defines the XML format of ECMA-269 services and events.
The Front End (FE) application conforms to the minimum subset of the
TR/87 specification defined for Office Communications Server 2007
interworking and those components necessary to support the next
generation SIP Contact Center requirements.
Figure 92 "Message sequence diagram - CSTA Session Establishment and
