Network interface (second)
A second network interface can be configured in the PBX. Accordingly, two IADs (Integrated Access Devices) can be directly connected to the PBX and configured. Requirement is a COMtrexx Business with inserted NET module.
The following possibilities for using two network interfaces can be realised:
External VoIP on LAN connection 2
At the connections LAN 1 and LAN 2, an IAD is connected in each case.
The external VoIP telephony is realised via LAN 2. There is no Internet connection at LAN 2.
The internal VoIP telephony and Internet connection are realised via LAN 1.
The data transmission can be optionally realised via a separate connection.
Internal VoIP on LAN connection 2
An IAD is connected to LAN 1.
The data transmission and external VoIP telephony are realised via LAN 1.
The internal VoIP telephony is realised via LAN 2.
VoIP completely on LAN connection 2
At the connections LAN 1 and LAN 2, an IAD is connected in each case.
The internal and external VoIP telephony are realised via LAN 2.
The data transmission is realised via LAN 1.
Configuration
