The time for change was high with our Edgevox system. We did not have high availability, technical support was always delayed, and there was a lack of features that drastically reduced our ability to communicate, like the status of other extensions, for instance. We found that 3CX not only saved us money on our previous budget, but we were still able to migrate to the cloud with the stability and support we were looking for.
