[reSIProcate] Sharing DUM State

["Nilay Tripathi" <nilay.linux@xxxxxxxxx>]

Hi,

DUM maintains state for each dialog/session. It is defined in class InviteSession.

What I am curious about is that, is there going to be any problem if we share this 
state through the handles? Which precisely means writing a public 'get' function and 
pulling out the 'state' enum into 'public'.

I feel this would be a good to have thing, for lets say that I want to integrate this to a 
minimalistic call-fsm. This would save from changing into the provided call-fsm and 
also need not maintain states separately. Of-course, state transition would not be 
allowed but re-usability of DUM states can make life simpler :)

Thanks in advance!!

Regards,
Nilay
