How to set emergency service location for 2 desk phones in different locations for same user?

[justinmarthaler]

What is the best strategy to provide up to date emergency service information for an individual who has two desk phones.  One desk phone is in the office and another desk phone is used nomadically as he switches from location to location.  For example, one week, he might be on a construction site in Louisville, KY and the next week he might be at a construction site in Chicago, IL.  Knowing the network details (public IP, private IP/subnet, etc.) is difficult and cumbersome to keep up to date.  When using the Zoom Workplace app, the individual is prompted for a new location, but that doesn't seem to affect the physical desk phone.  

Let me know if there is a good strategy for handling this type of situation.

Many thanks!
