Re: [Sip] INFO considered harmful

The big huge difference I have been trying to point out is that EVENTS
DEFINES SEMANTICS, whereas INFO doesnt.
MIME provides semantics and syntax that are independent of the type.
SIP events provides semantics and syntax that are independent of the
package.
INFO provides nothing.


INFO provides "minimal" but very important semantics: asynchronous data
reliably follows the established SIP path.
Huh?

Every new SIP method is reliable, it inherits the SIP transaction state machine for non-invite. Follows the established path? Every in-dialog method would have this property, it is method independent. Asynchronous? You can send any method at any time.

Thus, nothing you have pointed out above is different between INFO and any other new method we might introduce.
