I finally switched from T-Mobile Home internet back to Cox because TMO was not reliable, trying to reconfigure voip.ms to work again on my 200 and 2182.
If you have voip.ms on your obi 200 or 2182, did you use the standard config mentioned in the voip.ms wiki (http://[url=https://wiki.voip.ms/article/OBi_100/110_%26_OBi_200)? and is call encryption good to do?
Yes. I used the standard config along with TLS. Works great.
OBi config with TLS (https://wiki.voip.ms/article/OBi_100/110_%26_OBi_200#Configuring_a_Voice_line_using_TLS)
