The ConfigCenter Support Log  

The Support Log provides the supporter with information from the internal processes of the ServiceCenter:

  • Registration
  • Connection setup, release and exceptions
  • Call Routing
  • Used Ruleset
  • Emergency calls
  • etc


The Support Log provides filters for:

  • Time based selection: From – Until, From – Duration
  • Text filter
  • Registration events
  • Call events
  • etc.


The Support Log has a limited history. The history may last from a few hours up to some days. The length of the history may be different from VoIP switch to VoIP switch and depends on the length of log files and amount of logging events.


Note

The Support Log is tenant sensitive. This means a supporter of tenant A is not able to see events of tenant B!

Interpretation of a Support Log  

The interpretation of a "Support Log" is quite easy and straight forward. With a little experience one will be fast familiar with the interpretation.

ConfigCenter Trace  

The Trace provides the supporter with information from the message traffic between the VoIP switch and external VoIP devices, such as PSTN gateway, SIP CPE, SIP or MGCP telephones.

The Trace contains:

  • Session Initiation Protocol SIP registration and connection signaling messages
  • Media Gateway Control Protocol MGCP audit and endpoint control messages
  • Session Description Protocol SDP streaming media initialization parameters


The Trace provides filters for:

  • Time based selection: From – Until, From – Duration
  • Text filter


The Trace has a limited history. The history may last from a few hours up to some days. The length of the history may be different from VoIP switch to VoIP switch and depends on the length of log files and amount of logging events.


The interpretation of a Trace (PCAP formatted file) has to be done in an external application like Wireshark network protocol analyzer. Wireshark offers deep and rich VoIP analysis.


Note

The Trace is not tenant sensitive. This means a supporter of tenant A is able to see signaling messages of tenant B!

→ Due to this open display of information it may be possible that the Trace is not available for the supporters on a multi tenant VoIP Switch.

The ConfigCenter Call Data  

The "Call Data" lists the CDR of all incoming or outgoing connections or connection attempts. Extended filters enable the supporter to search for specific calls.


The "Call Data" has a limited history. The length of the history may be different from VoIP switch to VoIP switch and depends on the CDR storage length in the date base.


Note

The "Call Data" is tenant sensitive. This means a supporter of tenant A is not able to see events of tenant B!
