Is integration currently possible only with Dynamics 365 or also with Dynamics 2013?

I saw that 3cx can be integrated with Microsoft Dynamics365 but what about Dynamics 2013?
And if there is no such possibility, can it be implemented by creating a custom plugin?
Thank you for the answers

The integration works with Microsoft Dynamics 365 online. If you have Dynamics 2013 it's probably on-premise, which is not supported.
