I am using Dtek 50 on T-Mobile network. When I try to make calls on my Dtek using google voice it says "Call not sent" and the person I am trying to call sees my t-mobile number on their caller ID. I tried uninstalling and reinstalling Google Voice application as well as rebooting the phone.
I have been successfully using Google Voice and t-mobile on my Samsung S7 Edge for a while.
Any other suggestions on how this can be fixed?
