Subject: Virtual switch operation

Can anybody on the list point me in the direction of information on how SIP
performs a virtual switch type function.  I.e. a server has the ability to
direct an incoming call to an IVR and when an agent becomes free, to
re-route the call to the agent.  Possibly using some out of band technique,
the server could provide some IVR collected information to the agent.  Then
maybe later re-route the call to some one else (more than likely in my
experience!).  I would like to do this without re-directs as I want to
maintain application specific information in the server relating to the call
which I feel would be difficult to do if the call was redirected.

Many thanks,

Pete
