3CX Session Border Controller

3CX SBC - a very popular utility (server) from 3CX, used to provide better communication, call security and traffic saving. Or just to quickly and conveniently connect office IP phones to a cloud installation of 3CX PBX on Google, OVH, your own free 3CX hosting or in your cloud infrastructure.

The latest 3CX SBC update significantly improves server performance. Firstly, the number of RTP ports by default has been increased from 8 to 32. Secondly, the SBC service now automatically restarts in the event of an emergency stop. Other improvements and improvements:

The SBC service waits for initialization until it receives an IP address. Now there is no need to organize a connection via RDP or SSH in order to restart the service manually.
