Subject: [Linphone-users] There is no video in IOS app for 3rd party software, in iphone device

I have successfully installed Linphone on my Iphone 6 device, through this very helpful source ( The app is deployed in my device, I’ve configured it to use “” voip server online, and works like a charm. I can place calls and send messages. I cannot, however, place video calls. There is no video, whether I start an audio call and initiate video feed, or if I start a video call from the start. It doesn’t work. I am using linphone on Iphone, and a 3rd party app in the desktop. If I use linphone also on the desktop, the video call gets established but with POOR quality (another problem to solve later on). I wan't to use linphone with 3rd party software, what needs to be done?

Can you please help me solve the issue? I’ve configured my liblinphone-sdk for non third party, as there is a chance for commercial licensing later on. Linphone sdk has the following configuration, and I am surprised video does not work at all:
