These changes have been shown to help mitigate this problem in the majority of cases. This mechanism will trigger immediately if the impacted voice port is an analog FXO port. For other voice ports, a delay in the detection will be present and it is possible to see the symptom of this problem before the recovery code triggers.

Note that the reset mechanism will cause any active calls utilizing the DSP in question to be dropped. It is recommended if running with modules which can be impacted by this issue to upgrade to a release of software which contains the changes in CSCse Note that this output is sent at debug level and it is recommended to enable either syslog or logging buffered on the gateway. Logging buffered on the gateway is enabled through the global command logging buffered debug as an example to set the logging buffered to use 50K bytes of processor memory for logging.

The output of the log can be seen with the exec command show log. A calls B. B does an at-alert transfer to C. While C is ringing, B does a ringing pickup on C's extension.
