Chapter 3 Configuring the Telephony Settings on the VG248
Disabling Cisco Fax Relay
Disabling Cisco Fax Relay
The VG248 supports Cisco fax relay. Cisco fax relay provides a more reliable
method of transporting fax data over the IP network rather than sending the fax
information as a voice call. However, the terminating device must also support
Cisco fax relay.
By default, Cisco fax relay is enabled on the VG248. However, follow these steps
to disable it:
Step 1 From the main menu, choose Configure.
Step 2 Choose Telephony.
Step 3 Choose Fax relay.
Step 4 Choose one of the following:
• Enabled
• Disabled
Reverting to Previous Configuration
By default, the VG48 ports identify their configuration using TFTP. This
configuration determines the Cisco CallManager system to which these ports
connect.
If persistent TFTP problems prevent the VG248 from retrieving this
configuration, the VG248 ports can revert to their previous configuration. This
enables the ports to connect to the Cisco CallManager system with which they
were previously registered.
By default, the VG248 automatically reverts to the previous configuration if the
ports fail to connect via TFTP. To disable this functionality, follow these steps:
Step 1 From the main menu, choose Configure.
Step 2 Choose Telephony.
