15.14 SIP ALG
If you click Advanced in the top navigation menu and then select the SIP ALG link, the following screen appears.
The UltraLine Series3 includes a Session Initiation Protocol (SIP) Application-level Gateway. SIP is a signaling
protocol used by multimedia applications, most commonly a Voice over IP (VoIP) system. This ALG enables use
of SIP devices behind your firewall without the need to create pinholes or custom firewall rules for this specific type
of traffic.
To enable SIP ALG, select Enabled from the SIP ALG drop-down list. Then, click Apply to save the setting.
NOTE: Do not enable this setting unless your service provider instructs you to do so.
15.15 UPnP
If you click Advanced in the top navigation menu and then select the UPnP link, the following screen appears. This
feature advertises the presence of your Router on the LAN. Universal Plug-and-Play is a networking architecture
that provides compatibility among networking equipment, software and peripherals. Products that have UPnP can
seamlessly connect and communicate with other Universal Plug-and-Play enabled devices, without the need for user
configuration, centralized servers, or product-specific device drivers.
To configure UPnP enter the desired values and then click Apply to save the settings.
