FXS Ports
Use the
Configuration > Ports and Trunks > FXS Ports
page to enable the phone
(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.
SIP/BRI Trunks
Use the
Configuration > Ports and Trunks > SIP/BRI Trunks
page to enter 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
PBX/
Key System
page.)
About SIP/BRI Trunks
•
The Cisco UC320W supports up to 12 simultaneous calls across all trunks
(including FXO and SIP/BRI trunks).
•
To configure the dialing prefix for outbound call routing through your FXO
trunks and SIP/BRI trunks, see the
Outbound Trunks
page.
•
To enter the phone numbers and configure the inbound call routing for these
trunks, see the
Inbound Calls
page.

After applying your configuration, verify your settings by placing outbound
calls through this trunk. Also use an external phone such as a cell phone to
place a call to the phone numbers for this trunk.
