Client of mine installed SBS 2003 onto their network. The lan range is 172.26.92.x. We installed a broadband solution for them going out on a second network card.
They then got a company to install a VOIP solution in for all their branches as well as routers. They VOIP is not working - apparently the ISA server or this sbs box is preventing traffic between the branches. The branches have been setup on ip ranges 172.26.93.x, 172.26.94.x and so for. There are routers between the branches on 10.1.3.70 and 10.1.3.65 and so forth.
What do i need to do to the SBS server to ensure that these ranges can all "see" each other?
