Following is a nice layout of the Route Patterns, the Partitions, and the Route List/Route
Group/Gateway.
Slow Server Response
Slow response from the server could result if the duplex of the switch does not match the duplex
of the Cisco CallManager server. For optimal performance set both switch and server to
‘100/Full.” We do not recommend using “Auto” on either the switch or the server. You must
restart the Cisco CallManager server for the change to take effect.
Reorder Tone Through Gateways
Users placing a call through the gateway might get a reorder tone if they are attempting to make
a restricted call or call a number that has been blocked. A reorder tone may occur if the dialed
number is out of service or if the PSTN has an equipment or service problem. Check to be sure
the device giving the reorder tone has registered. Also, check your dial plan configuration to
ensure that the call can be successfully routed.
Steps for troubleshooting reorder tones through gateways:
1. Check the gateways to ensure that you are using the latest software loads.
2. Check CCO (Cisco Connection Online at www.cisco.com) for the latest software loads, new
patches, or release notes relating to the problem.
3. Start an SDI trace and recreate the problem. Reorder tones could be the result of a
configuration issue with location-based admission control or gatekeeper-based admission
control where the Cisco CallManager might limit the number of allowable calls. In the SDI
