Dial-Peer Configuration Table
The next step in creating dial peers is to create a dial-peer configuration table. Under the following
headings, show data for all of your gateways and associated dial peers. Table 18 is for the simple
gateway-to-gateway scenario described earlier; your own will be far more complex.
Tip Consult the references at the end of the chapter before you create a dial-peer configuration table. See
also Voice over IP for the Cisco AS5300, available online at

Configuring Echo Cancellation on the Voice Feature Card
The echo-cancel enable command enables cancellation of voice that is sent out the interface and
received back on the same interface; sound that is received back in this manner is perceived by the
listener as an echo. Disabling echo cancellation might cause the remote side of a connection to hear an
echo. Because echo cancellation is an invasive process that can minimally degrade voice quality, this
command should be disabled if it is not needed.
For the voice feature card, software echo cancellation is the default configuration—G.168-compliant
echo cancellation is enabled by default with a coverage of 64 milliseconds. Hardware echo cancellation
is not available.
