[SIPForum-discussion] INFO method

[Greier, Tom]

Wouldn't a RE-INVITE be used for keep-alive?

	Hi all,
	

	
	I am curious about usage of INFO method. Actually, I need
advice. I haven't noticed any practical solution that uses this method
yet. Like it's not popular method for using today. Maybe I am wrong, but
I have feeling that MESSAGE within dialog could do the same job;
exchange signaling information among parties.
	
	

	My intention is to send some additional signaling information
important for upper application immediately after SIP dialog (with
INVITE) has been opened. Questions are: What should I use? What is the
preferable method today for such things? Is there some RFC that obsolete
RFC 2976 (INFO)?

	Regards,
	Darko
