We turned to Exolve for connecting to a virtual PBX and simultaneously set up an IVR voice menu for customer support. Communication for registered employees is free, which is very convenient, especially since many work remotely. There is the option to record calls and detailed analytics. We have been working with them for two months now, and the connection has been stable so far. As for the downsides, the website sometimes seems too large and confusing, but it does provide detailed descriptions of all services and has a convenient search feature. In case of any unclear moments, you can always get help from a manager. Pros: quality communication, a wide range of services, good technical support. Cons: a complicated website at first glance, lengthy security checks.
