As discussed in the previous article, as Mteja runs on the Internet connection that you use. Your user experience is directly influenced by the quality of Internet Connection among other aspects.

Mteja's call centre platform has certain parameters critical to ensuring a good call experience.

Below are the conditions we monitor:

Jitter: Jitter is when certain packets of information are sent out of order, leading to a jumbled conversation. Simply put, jitter is when the information arrives at the recipient’s line out of order — they will not be received in the same order in which they are sent.

remote Inbound Jitter - refers to the caller on the mobile device, while inbound Jitter - refers to the user on the Mteja dashboard.

This is measured in the milliseconds of delay, and if the jitter is beyond 15 milliseconds delay, your call quality will degrade massively.

Packet loss: refers to when “packets” or pieces of data travelling across a network do not reach their end destination. The end result of these packets failing to reach the opposite end of the network communication leads to missing data, in a call it would lead to missing pieces of the conversation.

remote Fraction Lost - refers to the caller on the mobile device, while fraction lost- refers to the user on the Mteja dashboard.

For good audio quality, packet loss should not exceed 1%, although up to 2.5% is OK. From 5% - 10%, the audio quality will be noticeably degraded.

Round trip time: is a measurement of the time between a packet being sent and an acknowledgement being received for that packet. Round trip time is measured in milliseconds, the threshold is 300 milliseconds, above this, the audio delay adversely affects the call experience.

Where to view Jitter, Packet drop and Round trip time on Mteja

During a call, click on the call statistics hyperlink button

Scroll down the webphone tab, to see the different statistics

i) Packet Loss

ii) Jitter

iii) Round Trip Time

Lastly, the record of the call statistics is available at the end of the call when activated.

How to activate call statistics for your calls

Click on the settings icon on the webphone

Under the Advanced settings tab, check the Advanced call stats buttons

  • Off
