E911 Support
Ubigate iBG2016 supports an E911 feature. E911 is an emergency telephone
system capable of automatically displaying the callback number(and in some
cases the location) of a person who dials emergency call numbers(911) to
request emergency help from public safety agencies.
The North American emergency E911 phone system consists of a voice
network that is built largely outside of the normal public switched telephone
network(PSTN) on which common voice traffic rides. They are treated
specially because they are routed differently within the PSTN than normal
traffic. Calls to emergency services are routed based on the calling number,
not the called number. The calling number is checked against a database of
emergency service providers that cross-references the service providers for the
caller's particular location. When this information is known, the call is then
routed to the proper public service answering point(PSAP), which, in turn,
dispatches those services for the caller's location.
High Availability of Voice Feature
As enterprises extend their IP telephony and high-value application
deployments from central sites out to remote offices, one of the factors
considered vital in deployment is the ability to cost-effectively provide backup
redundancy functions at the remote branch office. However, the size and
number of these small-office sites precludes most enterprises from deploying
dedicated call-processing servers, unified messaging servers, or multiple WAN
links to each site to achieve the high availability required.
Ubigate iBG2016 provides high availability voice solution for the below case:
