Run Site Qualification Test<\/div><\/h2>

Wait for installation to complete; the tool runs automatically and displays the following screen:<\/div><\/span>

Don\x27t use other apps or refresh the screen while the tests are running. The duration of the test is directly related to the number of calls being simulated. On average, results are presented after about 3 minutes.<\/div><\/div>

<\/div><\/div><\/div><\/div><\/li>

Once tests complete, view the displayed results, which are categorized into 3 columns:<\/div><\/span>

Capacity Results<\/div><\/b>: This test confirms whether the number of specified devices can perform voice calls at the same time. A real\u002Dtime bandwidth capacity test is also performed and a \x27Max supported calls\x27 value is presented which represents the maximum number of One Talk devices that can successfully make calls simultaneously over your internet connection. This value is of importance for determining whether or not you may have room for future expansion.<\/div><\/li>

±·±ð³Ù·É´Ç°ù°ìÌý³Õ´Ç±õ±ÊÌý³§³Ù²¹³Ù¾±²õ³Ù¾±³¦²õ<\/div><\/b>: This test conducts a real\u002Dtime evaluation of your network conditions and provides a report on them. Four variables are reported on, and all are important factors in the performance of the One Talk service:

Jitter up\/down<\/div><\/b>: Some packets take longer to travel from one system to the other. Jitter values should always be under 5 milliseconds for optimal voice quality.<\/div><\/li>

Packet loss up\/down<\/div><\/b>: When some pieces of data fail to reach their intended destination. For One Talk users, packet loss presents in the form of poor voice quality or noise on the line, amongst other things. This value should always be 0.1% or lower.<\/div><\/li>

Connection latency<\/div><\/b>: The time it takes for data to travel from the sender to the receiver and for the receiver to process that data and respond. Latency determines how fast the data can be transferred from the end point to the network and back. High latency creates bottlenecks in any network communication. It prevents the data from taking full advantage of the internet connection and effectively decreases communication bandwidth. The impact of latency on network bandwidth can be temporary or persistent, based on the source of the delays.<\/div><\/li>

²Ñ°¿³§Ìý³Ü±è°À/»å´Ç·É²Ô<\/div><\/b>: Mean Opinion Score (MOS) gives VoIP testing a number value as an indication of the perceived voice quality after being transmitted and compressed using codecs. This measurement is the result of underlying network attributes that act upon data flow and is useful in predicting call quality. It is the best value in determining issues that can affect your One Talk voice service quality.<\/div><\/li><\/div><\/ul><\/div><\/li>

Required ports for One Talk<\/div><\/b>: This test performs an analysis of the ports and protocols used by One Talk devices to determine whether the security devices (e.g., firewalls, etc.) protecting the business have been configured properly to allow One Talk devices to register, authenticate and provide service.

Ports used by One Talk desk phones<\/div><\/b>: 123, 443, 5061<\/div><\/li>

Ports used by One Talk Mobile and Desktop Clients<\/div><\/b>: 143, 443, 444, 991, 5061<\/div><\/li><\/div><\/ul><\/div><\/li><\/div><\/ul>

View the summary table at bottom of the test results screen (example below).<\/div><\/span>

This table is intended to be used as a reference for the results published by the tool to help the user understand them.<\/div><\/li>

Results in green indicate that their One Talk devices will have a high\u002Dquality experience.<\/div><\/li>

Results in yellow indicate that users may experience problems when making or receiving calls and voice quality could experience degradation. Because the codec used by One Talk devices (AMR\u002DWB) is adaptive, it can make adjustments as needed in order to adapt to fluctuations in the quality of the internet connection.<\/div><\/li>

Results in red indicate serious problems in the internet connection that require immediate attention. If items in the \x27Required Ports for One Talk\x27 section are red, proper analysis must be conducted to determine whether those blocked ports are relevant to the One Talk service (i.e., mobile and desktop app clients use ports that desk phones don\x27t).<\/div><\/li><\/div><\/ul>
