The UA registers with ser at 14:26:39 It receives an invite, which gets canceled and a bye/ok is completed at 14:27:30
Just to avoid any confusion, this invite/cancel was generated by myself. I mentioned it here just to be complete.
UDP pings cease to enter the private network via the nat router at at 14:32:36 The UA re-registers at 14:56:37, and the udp packets start again, and the above cycle seems to be repeated.
