Hi guys,
I have a VoIP adapter produced initialy for Sunrocket provider.
It's fully unlocked. I can access all the settings.
The funny thing is that...I don't know what all the settings are

Before this, I had a Grandstream HT486 and was a joy setting that up.
This one....a nightmare

I am attaching 3 pictures from the menu, maybe somebody can guide me through those settings.
I called the adapter by IP with X-lite and the phone rings, no sound though.
Any help is good help.
Thanks.
