Lync Online - Transport Reliability IP Probe (TRIPP Tool) 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.
Microsoft Office Communications Server Remote Connectivity Analyzer The Office Communications Server Remote Connectivity Analyzer is a great tool for performing testing, troubleshooting, and diagnostics on Communications Server 2007 and Communications Server 2007 R2 deployments, and should server as your initial stop when attempting to troubleshoot a Communications Server Edge Server connectivity issue. The Office Communications Server Remote Connectivity Analyzer is a web site that Communications Server administrators can use to validate and diagnose end-to-end Communications Server scenarios. The site simulates multiple Office Communications Server client access scenarios from outside the customer's infrastructure and reports whether the test was successful. If the test fails, the tool informs you exactly where in the process the test failed, as well as provides troubleshooting tips about resolving the issue.
The Microsoft Online Services Diagnostics and Logging (MOSDAL) Support Toolkit performs network diagnostics and collects system configuration, network configuration, and logging information for applications that are used to connect to Microsoft Business Productivity Online Standard Suite (BPOSS) or to Microsoft Office 365. The logs and diagnostic information that the tool generates provide data that helps technical support professionals troubleshoot configuration, network, installation, and other service-related issues. The MOSDAL Support Toolkit collects log files, registry keys, and configuration settings that would otherwise require time-consuming and labor-intensive collection by using separate tools.

Your network contains four servers. The servers are configured as shown in the following table.

Each office has a local connection to the PSTN.
The peak usage statistics are shown in the following table.

Every audio call consumes 100 kilobits per second (Kbps). You plan to replace the PSTN connection with a centralized SIP trunking service. The service will contain a SIP trunk in the Seattle office and a SIP trunk in the Amsterdam office. The solution will use least cost routing. You need to identify the maximum amount of bandwidth that will be used by each SIP trunk. What should you identify?

Since both SEA and ASD have SIP trunk to internet.
NA calls: Redmond 10 *0.5 =5 Seattle: 100*0.8=80 Amsterdam: 50* 0.2=10 Berlin: 20 *0=0 Paris: 20*0.5=10 Total: 105 * 100K = 10,500 kbps
Eu calls: Redmond 10 *0.5 =5 Seattle: 100*0.2=20 Amsterdam: 50* 0.8=40 Berlin: 20 Paris: 20*0.5=10 Total: 95 * 100K = 9,500 kbps
Box 1: 9,500 Kbps Box 2: 9,500 Kbps
Transatlantic calls:
Amsterdam: 10
Berlin: 0
Paris: 10
Seattle: 20
Los Angeles: 5
Total number of transatlantic calls: 45
Total bandwidth needed: 5760 Kbps (45 x 128 kbps)
Amsterdam: Amsterdam+ Berlin+ Paris calls to north America: 50 calls x 20% (calls to N.A) x 128 kbps + + (berlin)+ 20 x50 x 128kbps equals 1280 Kbps + 1280 Kbps equals 2560 Kbps
Seattle: 100 calls x 20% (calls to Europe) x 128 kbps equals 2560 Kbps
