This reliability tool tests your Internet connection to a Microsoft Lync Online Service data center and measures the response times, bandwidth, allowed ports, route taken, and overall connection quality with respect to Real Time Media. The results can help you evaluate your network configuration for potential use with the Microsoft Lync Online Service. This tool does not engage any of the offerings from Microsoft Lync Online Service. Instead, it focuses on the quality of your connection to the Microsoft Lync Online Service data center.

Details

This tool helps you understand the quality of the Internet connection between your environment and Microsoft Online Services. It does not measure your environment compatibility with Microsoft Online Services. The tool performs three tests:

  • Speed: This probe measures your actual download and upload speeds, quality of data, and TCP efficiency. It uses TCP/443 for download testing and TCP/443 for upload testing.
  • Route: This probe measures your route quality, including packet loss, latency, round trip, and ISP peering points. It uses Internet Control Message Protocol (ICMP).
  • VoIP: This probe measures your expected VoIP quality by measuring UDP loss and jitter. It uses UDP/50021 and UDP/50022 to simulate audio streams with G722 codec at 50pps.
  • Firewall: This probe tests whether your network firewall is blocking ports necessary for the Microsoft Lync Online Service. It tests with outbound connections to TCP/443 for Client Signaling plus AppShare, TCP/5061 for Federation Signaling, UDP/3478 for Media Access, and subsets of UDP/50,000-59,999 for Audio/Video transport.

Comments
  • Is there a logfile created with this tool that I can pass on to support?

  • Is there a version of the tool that doesn't require Java? You know, in the light of latest java security issues.

  • I see that this KB/Support article lists two additional locations, Hong Kong and Singapore - support.microsoft.com/.../en-us.  Any chance you could add these to this blog post, as it's great to have a single link to point my colleagues to? This TRIPP tool is invaluable, BTW!

  • Question - should we be testing to the site closest to the user...or where the user's pool is at?

    My understanding from MS 365 support is that user's pool is based on where the tenant it at.  So in the case of a US company, they'll be closest to Texas for example.  And a user that on that tenant will always have their traffic traversing back to Texas to get to the pool.  So, they really should always be testing based on the site closest to their pool, not where the user is located at.  Correct?

  • Not working with the latest version of Java. The application is not sighned

  • Too bad application is not signed. Is there workaround?

  • With latest version of java, perform the following:

    1. Navigate to the java control panel
    2. Click on the 'Security' tab
    3. Click on 'Edit Site List...'
    4. Click 'Add' button
    5. Add the location URL in question (For San Antonion, TX: http://trippsn2.online.lync.com/)
    6. Click 'Add' button again to save the setting
    7. Click 'OK' to exit the Exception Site List menu
    8. Click 'OK' to exit Java Control Panel
    9. Re-start browser and test

    The quick option (not recommended) is to lower your Java security setting from the default, 'High' to 'Medium' in the Java Control Panel.

    Cheers!
