T-mobile 5G Home Internet and VoIP - Needs Router

Our VoIP line worked fine with T Mobile 5G home internet gateway/router for 6 months until recently when we were not able to call out.  Our old Obitalk 200 voip phone adapter was unable to call out as it could not get a IP. 
 

All I did was install our 10 year old router between the phone adapter and the T-Mobile gateway with ethernet cable and it worked again.   Make sure the router you install either doesn't use the same ssid as tmobiles gateway or just turn off the routers WiFi radio so it's not conflicting with  t mobile's gateway. 
 

Im assuming the T-Mobile gateway received a update and started to block the adapter.  Hope this helps, I only tried it after seeing one other post about a magic jack customer doing the same.

    Thanks for your suggestion!  Could you please share the model of the T-Mobile adapter you have in your house and the VOiP rovider/hardware you are using?  I have  run into the same issue with my mother's new service as her Linksys VoIP adapter would not get a dial tone directly connected to the 5G tower (white rectangular with screen on the front.)  I connected an OpenWRT router in between and the phones get a dial tone, however they are unable to dial out or receive calls still.  Wondering if there are any specific port settings that need to be setup on the router to get  VoIP to work

     

    Thanks!!
