3CX does not provide technical support via these forums. Many problems can be solved by obtaining a 3CX support package, which are very competitively priced. Support packages can be purchased here. We recommends buying 3CX via a partner that will be able to support you.

We will give pointers but we can not guarantee interoperability with all providers. These items involve 3rd party products and networks outside of the control of 3CX and support may only be available via Best Effort Professional Service Fees at an hourly rate. Pricing for our support packages and how to buy them can be found here FAQ's in relation to our Support services 1. Why do you not provide evaluation support? Installation and configuration of a complete VoIP Phone System takes time, and its not possible for this to be done prior to purchase of the relevant support services. Keep in mind that 3CX Phone System can not be compared to a simple office package, say a drawing program, which is easily installed and supported. 3CX Phone System is a complex program, that has to work together with phone hardware, voip providers and gateways. This configuration support cost time and can not be given free of charge. 2. Why do you recommend particular VoIP providers? We have no particular preference for VoIP providers, however we have partnered up with leading VoIP providers in order to be able to ensure interoperability. These providers have pledged support for our product as well as given us a test account so we can test each of our builds against the VoIP providers. Unfortunately not all VoIP providers stick to the RFC standard and therefore its not possible to guarantuee interoperability with all voip providers. We actively look for VoIP providers that are ready to partner with us.
