5.1 Network Interface

The Network – Network Interfaces menu helps you manage all network interfaces available in the PBX. In addition to the CPU interface, there are Ethernet interfaces of VoIP boards. The bit rate of all the interfaces is 10/100 Mbit/s. These interfaces are used for communication with the PBX and SMTP clients, for signalling and RTP streams of VoIP calls. Having been opened, the Network – Network interfaces menu displays a list of Ethernet interfaces of the PBX on the left and selected interface settings on the right. With the CPU interface, the options are as follows:
