Syslog and Debug Recording

For debugging and troubleshooting, you can use the device's syslog and/or Debug Recording capabilities:

■

Syslog: Syslog is an event notification protocol that enables a device to send event notification messages across IP networks to event message collectors, also known as syslog servers. The device contains an embedded syslog client, which sends error reports / events that it generates to a remote syslog server using the IP / UDP protocol. This information is a collection of error, warning, and system messages that records every internal operation of the device.

■

Debug Recording: The device can send debug recording packets to a debug capturing server. When the debug recording is activated, the device duplicates all messages that are sent and/or received by it and then sends them to an external server defined by IP address. The debug recording can be done for different types of traffic such as RTP/RTCP, T.38, and SIP. Debug recording is used for advanced debugging when you need to analyze internal messages and signals. Debug recording is also useful for recording network traffic in environments where hub or port mirroring is unavailable and for recording internal traffic between two endpoints on the same device.
