There is a wonderful dumb moment in E911 as point 26 in Business 2.0′s dumbest moments in tech – February 1, 2006 where they quote Niklas Zennstrom, co-founder of Skpe as saying
“If there’s a burglar in my home, maybe I send an e-mail or a text message to the police instead of making a call.”
Now I suspect that Niklas many have been trying to say that in some situations it would be nice to have alternative ways to contact a PSAP and I would agree but we will always want voice as one way, and mostly likely the primary way, to contact a PSAP?
