The following Session Initiation Protocol (SIP) trace packets illustrate the call flows to accomplish the Communicator Web Access (2007 R2 release) Add Audio scenario.

The initial state is that User1 and User2 are in an instant messaging (IM) session and User1 asks to add audio to the session. User1 is using Communicator Web Access (2007 R2 release) and User2 is using Office Communicator 2007 R2.

Note:
Example packets have been redacted to increase clarity.

Communicator Web Access (2007 R2 release) User1 sends a SERVICE packet to ask for the conferencing capabilities of the Office Communications Server 2007 R2.
