9Line 911 is the cheapest option out there and does dynamic location updates for users on Jabber or desk phones including MRA desk phones.

They do rely on CER though and the user is prompted to update their location via the CER portal.  If you're on Flex licensing, CER is free/included.

This may get confusing though on the Shared DID.  You can use cheap DIDs just for E911 purposes I believe.

You're probably too small for UCM Cloud or Webex Calling Dedicated Instance which include Redsky E911 for free now as well.  Webex Calling also includes Redsky E911 now but you'd have to change your backend to no longer be CUCM-based.

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn’t require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).
