Cisco Unified Communications UC320W Administration Guide
Configuration > Ports and Trunks > FXS Ports
Use the
(FXS) ports on the Cisco UC320W and Cisco SPA8800 IP telephony gateways.
These ports support analog devices.
Note: Refer to the on-screen illustration for the location of the FXS ports, where
you can connect analog devices. You can position your mouse pointer over the
pointer icon to view the picture at a larger size.
Enabled: Check this box to enable the port. Uncheck the box to disable the port.
As a best practice, enable the ports only as needed, to avoid unnecessary impact
on the 24-user limit. This limit applies to all IP phones and all enabled FXS ports on
SPA8800 gateways. It does not include the built-in FXS port on the Cisco
UC320W.
Configuration > Ports and Trunks > SIP/BRI Trunks
Use the
settings for the SIP providers and BRI gateways that provide Voice over IP (VoIP)
services. You can add up to four different services.
Note: This configuration page is available if the System Mode is set to PBX or
Blend. It is not available in Key System mode. (For more information, see the
Key System
page.)
