[reSIProcate] Invite request and Cseq numbers

[John Draper]

12.2.1.1 of the RFC says:

"Therefore, if the local sequence number is not empty, the value of the 
local sequence number MUST be
incremented by one, and this value MUST be    placed into the CSeq 
header field"

If this is the case, then wouldn't I be seeing Cseq numbers increasing 
as the dialog
exchange is going on?

Take a look at these two "100" responses I'm getting back....

BY the way,  I'm getting back about 5 or 6 "100 Trying" responses...   
is this typical?
Also,  I'm not getting any callbacks to my "InviteSessionHandler" or 
"OutOfDialogHandler".
Shouldn't I be getting these callbacks,  even when I'm getting the "100 
Trying" responses?

Perhaps this is my problem,  my "InviteSessionHandler" is not getting 
"hooked up"
properly such that it's not getting these callbacks?  I didn't see any 
kind of
errors in the DEBUG logs.  Would I get them?
