Hi Kishore,
As RFC2976 says:
" The INFO method is used for communicating mid-session signaling
information along the signaling path for the call.
......
The INFO method is not used to change the state of SIP calls, nor
does it change the state of sessions initiated by SIP. Rather, it
provides additional optional information which can further enhance
the application using SIP.
There are no specific semantics associated with INFO. The semantics
are derived from the body or new headers defined for usage in INFO."
It is not allowed if you want to follow RFC2976.
Assuming it can be sent out-side of a dialog, it have no meaning by itself.
Some implementations use Message to carry some dialog unrelated information.
Reguards!
