Video calls usually become unusable long before they actually drop, say global broadband experts. India also happens to be the largest market for Whatsapp video calling globally, the company had said in the past, as internet users made some 50 million minutes of video calling every day in 2017 on the messaging app. “To stop video calls from dropping, at least 70-80% of India’s tower base needs to be fiberised, going forward,” said a senior tower industry expert, asking not to be named. Soni believes telcos need to invest much more in intra-city fibre infrastructure to improve video call quality.

The FaceTime video calling problem that Ookla identified as serverrelated can be a latency issue, for example. Lower the latency of a network, higher the internet speeds, and vice versa. The latency of a network is a measure of the delay a user experiences when his/her computer/smartphone tries to access an internet server.

“Given the poor fibre connectivity coupled with low intra-city fibre infrastructure penetration in India, ensuring a stable video call without drops is a challenge as data transmission primarily happens over microwave networks, which is not as stable and has higher latency levels,” says Nitin Soni, director (corporates) at global rating agency, Fitch. This happens, for example, during FaceTime or WhatsApp video calls. If the compatible firmware isn't available, install the October 10, 2017, security update for Skype for Business 2016 (KB4011159).Plus, data plans that offer low upload and download speeds also add to a poor video calling experience, including dropped calls.

Install the latest firmware version of your conference room device to make sure that it conforms with the NTP/RTP timestamp pairing. This causes the Skype for Business client not to recover from video freeze. However, some room device firmware does not provide valid Network Time Protocol (NTP)/Real-time Transport Protocol (RTP) timestamp pair in RTCP messages. Therefore, the Skype for Business client is expected to recover from network glitches automatically. In the situation of bitstream corruption or network loss, video freezes until the next keyframe. Recently the Skype for Business client has made a change to rely on the estimated send time to throttle picture-loss-indication Real-time Transport Control Protocol (RTCP) feedback. When you have a video call in Microsoft Skype for Business 2016, the video freezes with some conference room devices.
