We have been doing business with Kinetix for both telephony/internet and printing for two years and would highly recommend their services. Kinetix have always been exceptional with respect to speedy service, problem resolution and communication.
Furthermore, they were instrumental in getting fibre connectivity to offices that were previously unfeasible when applying directly to the service providers. They provide a hugely more effective and efficient point of contact than communicating directly with the service providers and have been invaluable at providing honest and solid advice, often recommending options that would be against their benefit, but good for us.
With respect to telephony and VOIP, Kinetix have advised and provided services in such a manner that we were able to stagger our migration and save substantial CAPEX investments at the outset, while still keeping everyone up and running with minimal disruption.
This letter serves as a reference regarding the service and installation we received from Kinetix with regards to our VOIP solution. Our company was looking for a reliable solution for VOIP after a poor experience with Digium/Asterisk. We found that Kinetix was very professional with the presentation of the 3CX product.
Our company, Nkwe Platinum (SA) (Pty) Limited, with registration number and address as per the above, have contracted Kinetix Connect through a SLA (Service Level Agreement) since April 2013. 
SybaWeb have been working with Kinetix for just over 2 years now and believe that they have been a tremendous asset to the company. This decision immediately provided better performance in terms of VolP and connectivity. Downtime, which in the past was a regular occurrence has been reduced to null.
