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

  • Speed: This probe measures your actual download and upload speeds, quality of data, and TCP efficiency. It uses TCP/50000 for download testing and TCP/50001 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/20000 and UDP/20001 to simulate 5 audio streams with G722 codec at 64 Kbps.
  • Firewall: This probe tests whether your network firewall is blocking ports necessary for the Strencom Lync Online. It tests with outbound connections to TCP/443 for Client Signaling plus AppShare and UDP/3478 for Media Access.

Disclaimer:  Depending on your network and security environment, not all tests may be successful. A test success or failure does not mean that your environment is compatible or incompatible with Strencom Lync Online.
