Does anyone know of any services/providers that offer connecting an analog modem (to telephone line) on a server? Thanks!
My friendly local full-service ISP/Colo, CoreNAP, has done this for me in the past (actually, something a bit trickier -- they ran a PRI line to our system, reconfiguring their PBX to split off some channels to resell).
They passed through their costs, of course, but the service was a lifesaver. Look for colo facilities that offer hands-and-eyes; they're more likely to be willing to offer more unusual one-off services as well.
