Dear Daniel,
Actualy, we want to force unregister user A while user B is calling him and user A has lost his network connectivity but his registration timer has not expired yet. According to that we have placed functions:
t_reply("480", "User offline"); to reply with 480 instead of 408unregister("location", "$ru"); to unregister user A
into file root at sip:/etc/ngcp-config/templates/etc/kamailio/proxy/proxy.cfg.tt2
more specific:
