The VOIP system are completely useless for any medium sized business. Completely unstable . The system resets itself which causes it not to work and doesn't allow calls to come through. Calls can't be transferred. The support for the system is virtually non existent . You can only gets support between 9am and 4pm. The support staff keep changing and are not able to resolve issues. We've been on the system for a year and pretty much needed to put one of our sales guys full time on the constant resetting of the phones, VOYS are unable to resolve any of these issues and don't seem to understand their own system. VOIP systems are supposed to simplify things. I miss Telkom !!!
