That's when my fun started as well. I was running behind a router with no ports forwarded and VOIPo had STUN enabled for me. As of Tuesday night, based on a post from Tim over on BBR, regarding problems with Symetric NAT routers, STUN and the HT502, I had VOIPo disable STUN and then forwarded their suggested ports. I've been solid since. I'm going to keep the ports forwarded for a week or so and see if the HT502 keeps its registration. If it does, I plan on disabling the port forwarding just to see if it makes any difference or not.
