I do understand that its a deregistration.  I want my Kamailio to remove

on Contact and Expires HFs in the REGISTER message.".  So it seems it would

I'm in the in reply_route looks like it is working off the reply.  In which
case it can't "see" the Contact and especially not the ;expires=0.  Is that

So is there a way to get at the original REGISTER request in onreply_route?
 Otherwise I guess I must use an avp to remember the request or something
like that?  Since in the 200 OK there isn't really enough information to
tell that its a de-registration.  Unless I can imply that from the missing
Contact header?  But I think not since if there were multiple registrations
