My calls drop at 4 hours, still no idea where the limitation is and no real testing. If I can plan for another long call I will try moving the VOIP gateway outside the firewall but I can't currently think of a limit that would be imposed by the firewall that I wouldn't hit with other long running connections like music streaming. Maybe I need to try and start a Skype call and let it run for 4 hours and see if it drops.
