Lync Online Transport Reliability IP Probe (TRIPP) is a web based tool which can be used to troubleshoot issues with accessing Lync Online.
This reliability tool tests your internet connection to a Microsoft Lync Online Service data centre 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 Lync Online Service.
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 the following 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 Signalling plus AppShare, TCP/5061 for Federation Signalling, UDP/3478 for Media Access, and subsets of UDP/50,000-59,999 for Audio/Video transport.
