We are a multi-site, multi-pbx, international environment. We are exclusively Avaya, mostly G3r's. At the present time, we are accessing our switches via data-mods to perform administrative tasks. We have the ability to go to IP, but our network security people feel that this would create a risk (we have had incidents of hacking within the company). I have been asked to find a way to provide a secure method of access via IP. So far, the only thing I have come up with is installing a small firewall at each switch and only allowing connections from known MAC addresses. As you might imagine, this is going to be very expensive. Is SSH available? Has anyone else experienced a similiar challenge? What did you do?
