Community here is the video showing address to address calll, here is the link>
https://www.youtube.com/watch?v=HzWDAnVEHoE&feature=youtu.beAnd like it´s been said there is a few bugs which will get sorted out on the coming updates.
Apologies for the less than professional video. We´ve been up for nearly 2 days.
And follow the steps posted below by MikeMike
FIRST:
Let's get you all using the VoIP Feature. 
FYI: Both of us DO NOT have port 5060 open forwarding selected.
However it works if you forward port 5060.
1-You will be creating the call Direct.
2-Go to the "Receive Address Tab" and create a new address.
Label it however you like. Might makes sense to designate it your VoIP Address.
3-Right Click the Address and choose the bottom option "Set VoIP Account".
4-Go to "VoIP Calls" tab and click on the "REGISTER" box.
5-Enter the Address you'd like to call in the "Direct Calling/IM" box near the bottom.
You will see two tiny boxes on the right. Click on the "Left Tiny Box" to dial.
(
DO NOT click the "Call Buddy" box)
6-Watch the "Call Status" box, You will see it say "Calling".
Whoever is Receiving the call has to accept the call by clicking "Answer Call"
that will show in the box above the "Call Status" box.
7-To hang up simply click "Hang Up".
ENJOY!
NOTE: The call goes through very fast nearly instantly.
Thanks Eurbids for all your hard work!
