At my workplace we have been allotted a few IP addresses by the ISP. I think currently one IP is accessible from the outside (by accessible I mean in a browser). Typing this IP into a browser gets you access to a website for employees/customers and this IP is currently assigned to a router we are using.
But, we want our VoIP server (sipXecs) to be accessible outside as well. Currently, external VoIP phones can access the server, but the sipXecs configuration site cannot be accessed outside. We want to assign sipXecs its own IP, and I need to figure out how.
Right now I think all the computers in the office are connected to a switch, and a router is as well. The router (just a standard Linksys) handles the network work. There is a whole bunch of stuff and messy wiring in the server room, but I lack the technical knowledge to tell you more I am afraid.
Currently, we think that the best way to get the sipXecs accessible outside is to buy a second router, assign this second router the other IP, and connect all of our VoIP phones to it.
Is that the best way to do it? Is there anything in particular I should be vary of? Any security measures that I should take? On that same regard, how easy is it for someone evil to access the network devices on an internal server. Like for example, we have an ATA box in the office, connected to the router, and with a local IP assigned by the router, how easy would it be for someone sneaky to access the configuration site of this ATA outside the network?
