SIP request OPTIONS in the middle of a dialogue.

Hello All,

I am aware that OPTIONS method in SIP will used to know the status and capabilities of proxy server which can be out-of dialogue.

My doubt is
Is it possible, that OPTIONS method can come in the middle of the dialogue too? If so What are the uses of OPTIONS method in the middle of the dialogue?

Please provide your answers...

Thanks.
