Probably the easiest is to have your INOC-DBA phone number ring not only the SIP phone on your NOC desk, but a couple of commercial gateways like Vonage and BroadVoice and so forth, which would not, under most circumstances, all be affected by the same outage. One hopes. They would then ring PSTN numbers for you. Another way around the problem, which has been the most common one historically, is to put the INOC-DBA phones on different DSL/cable providers' lines run into your NOC, as well as on your own network. Three phones, reached through three ASNs, and _something_ should ring. A third way, which only a few ISPs have done, is to run a separate infrastructure out to a few exchanges, just to support those VoIP calls. That probably only makes sense if you're doing it anyway, for broader VoIP peering. -Bill
