So fresh off of Enterprise Connect our telephony people have brought up the topic of Kari's Law - https://www.congress.gov/bill/115th-congress/house-bill/582/text - Our team was curious if anyone has this implemented with their instance of Skype for Business with Enterprise Voice? We're looking to gather up any best practices and lessons learned to help us in the implementation with this in our environment. Did you spend a lot of time educating your end users about this change and what the potential downstream effects would be? Did you work with local dispatchers to ease into the transition? Posted the topic in Skype for Business IT Pros as well to get input.

 

Thanks!

@Timothy Balk There were some states that already had a similar law on the books that prohibited having to dial 9+9-1-1 for emergency calls.  Kari's law is the codification of those state concepts for national purposes.  Properly designed and configured emergency calling configurations for S4B would have already adhered to the items in the legislation.

 

For on-premises S4B installations, the configuration for this is very straightforward.  Make sure your location policy is set correctly - 911 is the dial number and 9911 or 112 or 999 or 000 is the dial mask. Make sure your location policy is assigned a PSTN usage that will route out a GW local to the site.  Assign your location policy to your Network Sites.  Voila.

 

In case you need a reference, take a look at:

https://ucvnext.org/2016/06/multiple-e-911-number-support-in-skype4b/

 

Generally speaking, you should not have to make any ITSP or ISDN level changes with the phone carrier.  Most carriers/providers don't accept calls for 9+911 anyway - it was the PBX requiring the leading 9 for an external trunk selection.

Agreed, the set up should be pretty straight forward. Looking more for info on what to communicate and what to do leading up to making the required change to prepare. Should we work with local dispatchers to let them know when we are making the change to give them a heads up potentially? That kind of stuff...

@Timothy Balk 

If you're going to be making actual calls to emergency numbers for testing and/or validation purposes, then I'd suggest calling the non-emergency number for your locale first.  You can ascertain what, if any, specific requirements the PSAP has for those tasks and then work accordingly.  More often than not you're simply validating that a) the call completed and b) that the dispatcher sees the correct address information based off the caller-ID (PS-ANI).  Most PSAPs will be accommodating if you call one or twice for verification purposes, but I have seen in the past where others have been rather...difficult and annoyed and confrontational in taking continuous calls from the same organization.  There's no one size fits all unfortunately and it really does vary from city/state to city/sate.
