General Troubleshooting Information
Call Agent (CA) log files are located in /opt/OptiCall/CA[XYZ]/bin/logs directory, where XYZ is the
CA instance (for example CA146). If you need to call Cisco TAC regarding a call-processing issue, first
collect the log files from this directory if possible.
Troubleshooting the Timeout Queue
Problem: Due to a change in NCS protocol specifications, MGCP command timeout has increased by a
factor of 2.
Symptoms: Increased memory usage on slow networks and during major outages of MGCP devices.
Diagnosis: Memory usage returns to normal when network connectivity to MGCP devices is restored.
Resolution: Great care needs to be taken when provisioning MGCP-T-HIST and MGCP-T-MAX
parameters in ca-config table. If necessary, reduce the values of MGCP-T-HIST and/or MGCP-T-MAX
parameters. Note that MGCP-T-HIST must be greater than or equal to MGCP-T-MAX + 10 seconds;
otherwise the provisioned settings are ignored by the system (the system reverts to the default values for
these parameters).
Note
