I was wondering if anyone could help me please regarding moving to a 3CX telephone system. I’m a business manager in a medium size primary school with a current analogue system, 2 lines coming into the school and 10 handsets. A local provider has quoted me for new handsets and a 3cx system based on a 5 year contract. The price is quite steep for a small school and would like to go down the route of buying our own handsets, buying sip trunks and setting this up ourselves. How easy is it please to move away from your current telephone provider and to set this up yourself?
