Hi,
I was installing an OBI200 for my mother-in-law and got GV setup without issue. I decided to add Anveo E911.
I went through the whole process but it would never register. After digging into the advanced settings and comparing to the information at Anveo, I found the the automatically configured ProxyServerPort and OutboundProxyPort were not configured correctly by the process. I tried many, many times using different browsers and everything I could think of. The automatic process set them to 5060 but they should actually be 5010. After changing them manually, it registered and works. You can see the details in the attached screenshot.
It is all working now, I am just sharing to help people in the future, and maybe Obi/Anveo can fix the process.
Thanks,
Chris
