@ Tinkster, sorry for lack of info, to be honest, there isn't much info, as this is a brand new network, which was set up on monday, the VoIP is on its own line and on its own network, so its just straight out to the cloud, that is why I want to throw in a box to balance between 2 connections to the cloud.
Kamailo looks like a good option at the moment (thanks) Will read a bit about it and see if it will suffice.
@ OdinnBurkni, yea I found that thread, at 1st glance I thought it wouldn't apply to me, as he is trying to get load balancing to a switch, and I am trying to get load balancing to 2 routers, but now it is looking like the same thing.
Im sure this is enough info to get me going, thanks a lot guys
One more question: Would it be a better solution buying one of these? http://www.xincom.com/products/502/overview.php
Or could I achieve the same thing with linux? I already have a spare PC and line and router, so there would be no cost in going the software route.
