[OpenSIPS-Users] limiting multiple registrations

X-Lite/Eyebeam and a Polycom with 3.x SIP software on it are the only
two UAs I know of that deregister.  But I've hardly seen them all.  That
being said, I need to knock out any existing registrations on in the
registrar when a new, valid one comes in.  I'm not sure how one would do
that.  Is there a way to force an expiration before saving the new one?
Or, perhaps to outright delete it through a function of the registrar
module somehow?

I think that makes sense.. why is your UA not deregistering? 

If you are just removing power or plugging it in from one network to
another without properly unregistering, then I'd expect this behavior. 

I don't think the server would have any idea if the UA is unique or not.

Changing the Registration period to be lower might help you with your
problem.. But it's just masking the real issue, which is that the old
registration isn't being properly deleted.

	When registrar's max_contacts is set to 1, it appears a UA must
	deregister itself before it can register itself from another IP
	Otherwise the registration is rejected and a log entry appears
	indicating the maximum registrations has already been reached.
I'd like
	to limit the maximum amount of registrations to 1, but I need
any new
	registration to supercede an existing one.  Is there a
relatively easy
	way to do this, or do I need to manually search the location
	before saving each new registration?
