EMERGENCY RESPONDER IN A SCHOOL SYSTEM versus SRST

[JMCNEL]

We are a small school system and I was wondering if their is a requirement for School systems by law to have emergency responder configured on their network.

What is the pro's and con's from having ER configured on the network versus having SRST configured or would you recommending having both.

Any input would be appreciated

Cisco Emergency Responder  (CER) and srst are different things. 

First lets start with SRST.

In the event of a server outage phone register to the local gateway in SRST.  SRST should be implemented anywhere voip phones would be considered a life safety issue.  The local gateway should have PSTN access that when 911 is called the calls are routed to the proper PSAP and the PSAP sees ANI (Calling number) and the location of the call.  This should be tested from time to time to ensure it is working properly, and someone didn't mess up the config in CUCM or local gateway.

This requires a local gateway per building.

I would often make that case that SRST should almost always be configured.

Cisco Emergency Responder or the scaled back version in newer CUCM version is different all together and provides more robust way to ID where the 911 call was placed from. Often this can be tied to switch ports or other methods. 

As far as the legal requirements in the US it can vary based on the state.

Hope this helps.
