Jason, I agree with you that wireless allows more points of failure due to multiple reasons. I will look into ATA for the outdoor emergency phones.

Personally I would stay away from wireless for emergency phones as you are bringing in more points of failure and not to mentioned unlicensed spectrum for emergencies. Plus you’ll need power to these points unless you want to rely on battery/solar…. Which again seems risky for emergencies. Our plan has been to either keep an MD110 unit in place (at least on the main campus) and/or use the cisco voice gateways or ATAs, and/or bring in PSTN’s directly from a provider. It will depend on cons/pros and costs once we start designing that part. Though I think Philippe’s comment below is pretty interesting(or awesome), get it cabled with cat 5/6 and install a wireless AP, for the phone either wired VOIP or an extra cable for an analogue service. -- Jason Cook The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Philippe Hanset Sent: Wednesday, 22 April 2015 3:09 AM To: [email protected]<mailto:[email protected]> Subject: Re: [WIRELESS-LAN] Outdoor wireless emergency VoIP phone recommendation University of Tennessee, Knoxville has more than 60 of these code blue phones all over campus. I always thought “Too bad we didn’t synchronize an effort with the Telephone Services Department to locate outdoor Wi-Fi in it”. Those emergency phones have power and cat5 running to them!

Ideally, I am looking for a wireless (Wi-Fi based) outdoor emergency VoIP phone to replace our very old landline based outdoor phones. My initial research has not produced any good candidates yet as well I was wondering if anyone has had successfully deployed such a system at their location? Any feedback would be very much appreciated. We use Aruba APs and Cisco Call Manager in our network.
