Is there any documentation regarding how Microsoft Phone System/Calling Plans support enhanced 911 in areas where it is supported or emergency services dialing using Teams Voice?
I'm going to guess in the Direct Routing scenario this is handled by the SBC utilized when implementing this?
Potential Coffee in the Cloud Topic (please)?
Finally, I'm not expecting an answer here because I think it might be more of an edge use-case... For companies that utilize non-persistent client infrastructure to provide access to applications, is it expected for the users to manage their location in some way so that if 911 is contacted from a soft phone it broadcasts their location and properly routes the call to the emergency services nearby? For example, I'm from home office in Big City, USA... but i'm visiting branch office in Smaller City, USA - I would have to make sure that as far as Teams knows I'm in Smaller City instead of my default Big City Location.

But in summary, you assign an appropriate location per number, then in the case of making an emergency call there is some screening to ensure the correct location is identified first. I don't really know what form that screening takes.

Reading up on things and asking some telecomm individuals... I think I know what I'm trying to connect up.
For Direct Routing, the underlying PSTN provider is (I'm guessing) the entity in charge of managing it's location information that transmits over to the PSAP.
In Microsoft Phone System, adding in the locations via the steps above configures this information for the company it is providing service to - it can be used and updated down to the user number to provide full location information (down to the floor level of a building) to the PSAP. Essentially Microsoft Phone System provides Private Switch/Automatic Location Identification (PS/ALI) with the subscription.
Does that sound correct?

Hi @Timothy Balk ,
thanks for the feedback. I added a note for future updates to consider emergency calling.

@Thomas Binder Interestingly----dynamic location services is not mentioned in this conversation, nor is it in the main Teams documentation. As you consider emergency calling, be sure to consider mobile workers who use laptops offsite, cellular/smart devices, log into phones at remote locations, home phones, etc. it's a whole different level of complexity and planning than what is discussed in this column or the Teams docs.

@Timothy Balk So the PSTN needs to be told the source of the 911 call, and I am not finding that to be documented in the Teams docs for Direct Routing or Emergency Calling. I am working on using the SBC to do it, and it might require a 3rd-party as well....will update as i learn

@CBryars Yeah, totally going to be a fun ordeal figuring that out for at remote workers or individuals using the mobile app... but now that I think the mobile app might be easier be easy because MS could just pull off the GPS coordinates for that to assist with location and routing the Call. Or just with the app directly use the Phone part of the mobile device to make the call and do all the emergency flagging associated with the device.
