I have a problem to start video call with Zoiper on Android.
I am trying to reach it from Linux SIP client through Asterisk.
Both, VP8 and H264 don't work. There is no error message on linux client side, and no errors on Zoiper side but I can see only black screen.
Configuration of Linux client and Asterisk should be ok, because on Bria and Linphone video works.
How can I debud it on Zoiper side?
Thank you in advance,
