Network settings are configured from the menu “Configuration -> IP Settings”
This menu has 2 type of interfaces:
- Signaling Interfaces
- Media Interfaces
Signaling interfaces are used to carry SIP Signalling traffic.
- Primary Signaling Interface (eth0)
- Secondary Signaling Interface (eth1)
|SBC straddle two networks|| eth0 should have external IP address
eth1 should have a local IP address
|SBC behind a firewall|| eth0 should have local IP addreess
eth1 will not be used
Media Interfaces are used to carry RTP traffic.
The Media/RTP IP addresses can be the same as SIP IP address.
Media interfaces are special DSP’s (Digital Signal Processor) which are accessible through any Ethernet network any of the signaling interfaces is attached to. These media interfaces are sometimes embedded within a Sangoma PCI card (ie D500, D100 devices) and sometimes are completely stand-alone processors that are just attached to the same network (D150).
The recommended mode to use is Hidden
- Hidden mode provides a single Media/RTP address to remove network.
- Exposed mode Exposes DSP Media IP address to remote network.
