Diagnostic Testing

  • Last updated on

Use diagnostic tests available on the Configuration > Diagnostics page to identify common network configuration problems affecting call quality or system stability to assist with troubleshooting and support. Each test includes the following elements:

  • Run – Check this box to select a test to be run. All selected tests will be performed when Run Selected Tests Now is clicked.
  • Description – Test description.
  • Last Test Completed – Date and time that the test was last run.
  • Status – Displays test status: Passed, Failed, or Some Failed reflecting the test result.
  • Details – Display additional details, if available, by clicking on the Show/Hide link.

To run a diagnostic test,

  1. Select one or more test from the table, and then click Run Selected Tests.

    Depending on the number of tests selected, this may take several minutes.

  2. Once the test is complete, each test’s status updates. If any test fails, click Show/Hide to see details and possible remedies. The following tests are available:
    • Storage Space – Checks available storage space for firmware, voicemail, and the system as a whole.
    • Database Integrity – Performs a database integrity check and notifies you of any concerns, directing you to contact technical support.
    • Ping Default Gateway – Performs a simple ping test between the Barracuda Phone System and the default gateway. The ping time displays in the details.
    • DNS Resolution – Performs a DNS resolution test for each SIP provider whose host is a domain name. The details view notifies you if NAPTR or SRV records are not set up on the domain name in question.
    • Provider Ping – Performs a trace route for each SIP provider on the system. If the ping fails, a trace route displays along with some suggestions on possible solutions.
    • NTP Association – Tests the Network Time Protocol server configured for the system.
    • Inbound SIP Calls – Tests the firewall to make sure all the necessary ports are forwarded.
    • Outbound SIP Calls – Performs the following tests on each SIP provider:
      • Create A Provider – Verifies a provider can be added to the system.
      • Register to Diagnostic Server – Verifies the registration process using a Barracuda Phone System diagnostic server that is on the public Internet.
      • Outbound Call – Makes a sample test call through the Barracuda Phone System diagnostic server.
      • Two-Way Audio – Confirms that media (i.e. audio) flows in both directions on the test call.
      • Jitter – Measures the jitter on the test call.
      • Remove A Provider – Verifies a provider can be removed from the system.
