Configuring
Emergency Services
An Emergency Response Location (ERL) is defined as a location to which
an emergency team may be dispatched. The complete VCX system is
organized, from an emergency services point of view, into various ERLs.
For instance, telephones can be assigned unique ERLs based on a
geographic or physical location.
Each phone (uniquely identified by the assigned IP address) is part of a
unique ERL and each ERL is assigned a location-wide emergency callback
phone number. In addition, a set of emergency gateways are specified,
which are used to directly reach the emergency service provided in case
the Call Processor is down.
A set of ELINs are assigned to each ERL, so the phones in a particular ERL
have a pool of ELINs. An emergency caller is assigned an ELIN from this
shared pool. This association is used to callback the emergency caller. If all
the ELINs associated with an ERL are in use, the location specific
emergency callback number is used instead.
