I have several VOIP providers I play with in addition to my VOIPo being my primary. I have a router running Tomato firmware with an Asterisk box on the inside. I am not doing any port forwarding at all, just QOS.

It seems like if I get more than 4 trunks registering from my Asterisk box, I start getting strange drops and inability to register on any of them at random. If I get 4 or below, everything runs well. I was wondering if anyone else has seen this? I am running 1.21 firmware currently.

I suppose it could be something other than the router, but I have had plenty of trunks registered on other asterisk boxes at other locations and haven't seen this, so I assumed the router as the first place to check.

take care!
