Hello, I am migrating away from a 3COM V3001 NBX system. The issue is that my current ISP does not support SIP trunks and I will not buy a Gateway since we are also migrating out of this ISP in less than a year so I need to use my current NBX as a gateway for, let's say: a year. I have searched the forums and cannot find the correct procedure for this. Specially since the 3COM side is completely undocumented. Can anyone help me?
