With the VoIP proxy, you can use your LANCOM R&S®Unified Firewall as proxy for VoIP connections. In this case the SIP telephones have to register themselves with the LANCOM R&S®Unified Firewall. The SIP packets are then masked by the VOIP Proxy towards the Internet (NAT).
The VoIP Proxy does not prioritize SIP packets.
Under , you can configure the VoIP proxy for your LANCOM R&S®Unified Firewall:
| Input field | Description |
|---|---|
| Internal Net | From the drop-down list, select your local network interface that you want to use for phone calls. |
| Internet Connection | Select the Internet connection from the drop-down list which your LANCOM R&S®Unified Firewall uses to forward the VoIP connections. |
| Activate SIP Proxy | Select this check box if you want your LANCOM R&S®Unified Firewall to serve as VoIP proxy for the SIP. It can be reached on port 5060. |
| Forward data to an External SIP Proxy | Select this check box to forward VoIP data in the SIP to an external SIP proxy. |
| Address of External Proxy | Enter the IP address of the external SIP proxy. |
| Port | Enter the port of the external SIP proxy. |
To use the VoIP proxy, you have to enter the IP address of your LANCOM R&S®Unified Firewall with port 5060 in your VoIP devices. For further details, see the documentation of your VoIP terminal devices.
If you have modified these settings, use the buttons at the bottom right of the editor panel to confirm (Save) or to discard your changes (Reset). Otherwise, you can close the dialog (Close).
