Phones Moving Between Clusters


The following scenario illustrates how Cisco Emergency Responder (Emergency Responder) clusters work and how Emergency Responder treats phones moving between clusters:

Server Group A (SGA) has a phone (Phone_1) that is moving out of SGA.

Emergency Responder discovers Phone_1 in Server Group B (SGB).

The Unlocated Phones page in SGA display the phone in SGB.

If both the Emergency Responder servers (Publisher and Subscriber) in SGB go down, SGA still displays Phone_1 in SGB.

Calls made from Phone_1 during this time are redirected to SGB and Emergency Responder takes the same steps to route this emergency call when Emergency Responder servers are not there in SGB.

Phone_1 is also treated like any other phone in SGB when both the SGB Emergency Responder servers are down.

If Phone_1 moves to Server Group C (SGC):

It is discovered after the next incremental phone tracking on SGA and then in SGC.

The Unlocated Phones page changes the association of Phone_1 to SGC.

If Phone_1 moves back to SGA, it is discovered in the next incremental phone tracking and displayed under the corresponding switch port.
