Corrective Action
Talk at a lower volume while on a call.
When simultaneous and similar audio on both
sides of the call is detected, the card may try to
cancel this perceived "echo," causing audio and
echo problems. Try to avoid doubletalk.
Run the Network Qualifier to assess your data net-
work. Then verify that your data network meets the
minimum specifications (see
information).
Change the backplane configuration settings. See
page 6-173 for more information.
Check IP Connection IP Addresses on the local
and the remote nodes.
Verify that there's a Node IP Connection Group in
the target node's Node Trunk/IP Connection
Groups folder. Make sure there's an Off-Node IP
Connection in that NIPCG, and verify the IP
Address.
Check the License and premium features for Net-
working.
Check your internet connection, and Upgrade IPRC
Firmware to version 8.1.2 or higher.
Check your Internet connection.
Make sure the PRI Card is online, and enough B-
Channels are equipped.
Check reference clock list on this and other nodes.
Make sure license and premium features are valid
for networking.
Make sure firmware is up-to-date.
Verify that there's a Node Trunk/IP Connection
Group to the remote node.
Verify that the Node Trunk/IP Connection Group
includes the Node Trunk Group or Off-Node IP
Connection to the remote node Depending on the
type of programming.
Refer to the Help file for each programming area.
