Emergency 911 Operations
ShoreTel 6.1 Administration Guide B – 5
Each site should have at least one 911-capable trunk. If there will only be one trunk at
a particular site, that trunk should be capable of placing a 911 call. You should also be
aware that if there is only one trunk at a site, only one 911 call can be placed at a time.
Therefore, you should make sure you have enough 911 trunks at each site to
accommodate the (realistic) potential 911 traffic for that site.
Trunk Signaling for 911 Calls
When a 911 call is routed out an analog or digital loop-start or a digital wink start
trunk, the service provider is responsible for passing caller ID information to the PSAP.
When a 911 call is routed through a T1 PRI trunk, the ShoreTel System sends the
proper caller ID information to the service provider, and the service provider must
forward the information to the PSAP.
NOTE Contact your local telecommunications service provider to communicate your
911 implementation plans and have them approved. It is important to ensure
that the service provider will accept, and subsequently pass to the PSAP, the
caller ID information configured within the ShoreTel system. In some cases,
without proper planning, a provider will reject the caller ID information as
configured in the ShoreTel system and will simply pass the caller ID information
associated with the trunk to the PSAP. If this happens, the dispatcher may get a
number telling them to go to the wrong location.
NOTE User’s have a “home port” defined in ShoreWare Director. If a user is not at his
home port, it could change the caller ID number delivered to the service
provider on 911 calls.
For mobile workers who travel between sites, the user must have access to a 911-
capable trunk at every site. In remote locations, the user should use the 911 trunk
associated with that remote location.
