Our IT-C Voipcloud phone system is hosted in secure Tier 3 data centre, that has a proven record of 100% power uptime and complete 2N protection.
But let's say your internet connection does have an off day. You can simply take your IP phones, plug them into another broadband service and carry on as normal, using the same number. When things are up and running again, re-connect your phones as before and you're back in business with high quality phone calls.
Or, using the online portal, you could just re-direct your calls to any other landline or mobile.
