Activating the Voice Port
By default, configured voice ports are active. However, if you need to activate a
port because it has been shut down explicitly, use the no shutdown command, as
follows:
Gateway# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Gateway(config)# voice-port 4/0
Gateway(config-voiceport)# no shutdown
Gateway(config-voiceport)#
00:55:53:%LINK-3-UPDOWN:Interface Foreign Exchange Station 4/0,
changed state to up
To deactivate a port, use the shutdown command, as follows:
Gateway# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Gateway(config)# voice-port 4/0
Gateway(config-voiceport)# shutdown
Gateway(config-voiceport)#
00:55:23:%LINK-3-UPDOWN:Interface Foreign Exchange Station 4/0,
changed state to Administrative Shutdown
Sample Configuration
This section provides a sample configuration for sending a fax or a call from the
Cisco 2610 (a voice-enabled router) to the eight-port FXS module on a
Catalyst 4224, and vice versa.
Note You can substitute any voice-enabled router for the Cisco 2610 and any
Fast Ethernet interface connected to an IP network.
