Getting our telecoms right, was all about communication and support. The large telcos simply cannot and do not provide the level of support that Dial9 do. Their system is robust and plug in, then forget. It just works. Why need the support then? As you grow, you add to the system and mess around with it. Sometimes you forget the process; fortunately the people at Dial9 have limitless patience and give clear instructions. I'm not sure what else you could ask for. We would highly recommend them.
