Hi The solution below does work in deed the only problem is that if I use it and I am logged in at work and I want to use the service at home it wont let me. What I am trying to achieve is that the same user can not be online with two sip phones at any one time. Is there a way to force a logout a user at Location A, when a user at Location B logs in.

Setting it to 1, only the last registration will be active. modparam("registrar", "max_contacts", 1) You may experiment problems if the user put 2 devices trying to register at the same time.

Hello, I just added to svn a new function for registrar module: uunregister(domain, uri), see commit: http://openser.svn.sourceforge.net/viewvc/openser?view=rev&revision=5010 The patch is small and clean. Backport to 1.4.1 should be straightforward. This function should help you to achieve the desired behavior: if register has expires > 0 then call first unregister("location", "$tu"); then save("location"); The unregister() function removes all contact associated with the address in parameter 'uri'. I am looking also to actually enhance save() function to get a functionality like: - update the expires if there is a record with same contact - otherwise remove all existing contact and add a new one

to deal with some broken NAT/STUN devices, when you are sure there is a single phone, but each registration gets with a new port for each register refresh.
