My concern is this. If it's simply because the 911 call centres use an IP phone, then, sure, let's study the impacts of IP telephony. However, there is a very specific.... This is a cellphone. It's not an IP phone. You know, it utilizes multiple technologies, but this is not an IP phone. The Cisco phones we all have in our offices are IP phones. The landline you have at your house is not an IP phone. It's a very technical thing. I'm kind of geeking out here, because I worked in the industry.
I'm just making sure there won't be any issues coming up in the study because we only narrowly prescribed it to IP telephony when, at the end of the day, most people don't use IP telephones. The call centres might, but the person phoning the call centre looking for help is most likely not using an IP phone.
