Hi.
I have setup Linphone. I previously setup Ekiga a while back and was able to make and receive calls from and to Linphone & Ekiga using a VirtualBox VM. So calls seem fine. This webpage was also very useful for making sure the call audio was fine:

Problems:
I have no video in Linphone, it just shows a black screen.
I have video in Jitsi, but cannot setup either Linphone or Ekiga SIP addresses in it.
On a side note, I installed Linphone in Android and it constantly says 'Registration in progress' instead of 'Registered'.
Please help. Thanks.
