This time we will analyze whether it is better to buy or develop integrations. Many communication systems already provide integration with software and it is not always reasonable to develop it. On the other side, if a solution is not compatible with your requirements, then it is better to consider developing.
These integrations can be realized via built-in modules, third-party services, or middleware applications.
If the requirements above are met (Determining Integration Requirements), there is no reason to develop integrations from scratch.
To find out more about the available PBX or UC solutions, consult the website or marketplace of the application with which you want to integrate.
