list, enter a name for the node (optional), set the QoS monitoring option,
and enter comments if desired.
WARNING
If a remote node has IP Peer H.323 Gateway capability,
do not use QoS monitoring unless that node is also
running IP Trunk 3.01 (and later). No other IP Peer H.323
Gateways support IP Trunk 3.01 (and later)-formatted
QoS.
Unless both sides support IP Trunk 3.01 (and later) and
have it enabled, calls cannot be made to that node.
11 Click Apply. See Figure 126.
