Logging is important when tracking down problems. The settings on this page are designed to help you troubleshoot. When the system receives or sends a SIP packet, it determines whether the packet will be logged and which log level the event will have.

  • Log REGISTER: REGISTER packets deal with the registration of extensions or trunks, which can generate a lot of traffic. If you are not interested in the registration traffic, disable this setting (see Appendix B for more information on SIP messages).
  • Log SUBSCRIBE/NOTIFY: SUBSCRIBE/NOTIFY deals with message waiting indications (MWIs), the LED state, and other used subscriptions.
  • Log call messages:: These packets usually belong to an ongoing call (e.g., INVITE, CANCEL, ACK, BYE). When you enable the logging for one of the previous categories, the SIP packets will be logged on log level 7. If your log level is below 7, the packets won’t show up in your log.
  • Log Other Messages: This setting takes care of anything that are not part of the above 3 cases. When you enable the logging for one of the previous categories, the SIP packets will be logged on log level 7. If your log level is below 7, the packets won’t show up in your log.
  • Log Watch List (IP): The watch list filters the SIP packets by IP address. This feature is useful when you have a specific device that you want to watch in the system’s log. Enter the IP addresses into this field.
