My sandbox number does not work. If I call from a mobile phone, it says that the "number is temporarily unavailable".
When I call it from a landline (ringcentral) the call is completed, but the dial menu does not work and It ignores whatever I type.
I created another dev test account just to double check this and the new sandbox number works properly.
My application is ready and I just want to promote it to production, but I still need to make calls on this number to be able to complete all required graduation requirements. Additionally, the analytics takes too long to take effect after some action.
