=Overview=
'''A VoIP service needs power, working internet - if either of these has a problem you may be unable to make calls and unable to call Emergency services. Being aware of this and being prepared for such problems is essential.'''
'''FTTP in the examples...''' On this page the examples include a FTTP ONT - this is the optical device that is provide on fibre circuits by Openreach/CityFibre. Not all services will have an ONT. FTTC and ADSL may have a modem instead, or the modem may be built in to the router itself. The point is that all devices that are used to make the internet work will need to be connected to a UPS.
=VoIP Vs Analogue=
# Use a UPS - an uninterruptible power supply. - typically a heavy box that contains a battery that is kept charged up and will switch to battery power in the event of losing power.
#Use a mobile phone - Keep a mobile phone close to you and on charge - use this to make phone calls if you lose power.
'''Test that this works!''' 500VA UPSs from a brand such as APC are available for around £60 which will keep lower power devices such as a router and a phone powered up for a while.

*In our tests, to run an FTTC Modem, router and a DECT base station a 400VA UPS will run for about 45 Minutes.
*To last an hour, we'd suggest a minimum of an 850VA UPS, such as the APC 850VA model pictured here.
==What happens if my internet connection has a fault==
===Solutions:===
#'''Use a mobile phone''' - Keep a mobile phone close to you and on charge - use this to make phone calls if you
# '''Have a backup connection''' Having more than one connection to the internet is important, not just for calling emergency services. A second line, tethering to a mobile, a service that uses a different medium to your main connection (eg satellite) will help keep your internet connection resilient in case of a fault.
