I will describe the situation I encountered, there is a network built on routeOS. It has a telephony server under ip 172.31.20.10, there are also employees who need to work through it, all employees are located in different regions. The telephony server works like this, first calls the client, then calls the employee, and then connects them together, but since the employee is behind the NAT, it is logical that the server cannot contact the employee. tell me how I can better build a network in netmaker so that the server can reach the employee, thank you in advance
