[SIPForum-discussion] INFO message in SIP

[Stephen James]

The 18x has to include a TO tag as well to establish dialogue before the INFO 
can be sent. 
It is best that the 18x is sent reliably to ensure that it is received prior to 
the sending of the INFO.

That is an open issue (we had some discussions earlier on that ) but it should 
be 18x messages better than INFO. Since the state is not in confirmed . After 
the first 18x mesage, you can send INFO message backward.

Hi all,

Is it possible to send INFO message after sending 100 trying message from Server 
side

Invite                         Invite
----------------->     |    ----------------->
100 Trying                100 trying 
<---------------       |     <----------------
    INFO                        INFO
 <--------------       |      <---------------

Is this scenario correct..
