Phone number cannot be called in new sandbox site

[mklawiter]

Hello all!  Since migrating over to the new sandbox site I can no longer use flows that trigger off an inbound call.  The number that is assigned to my sandbox cannot be called.  Whenever I try I get a fast busy or a message that the number cannot be reached.  

I gave it a few days to see if it just needed to be initialized or something, but no luck.  Help would be appreciated!

Tanuj helped solve this one!  I had not registered the number that I was using to try and call into the sandbox.  I hadn't realized that restriction existed, so once I registered the number it worked perfectly.

Hi @mklawiter - Which country are you trying to use it from? I just tested the voice receive capability and was able to do so without any issues. Screenshot attached. 

Also, tried invoking a flow using incoming call as the trigger and found it to working without any issues.

I'm in the USA.  Calls to that number do not work from Webex Calling-registered phones, cell phones, or anything else that we've tried.  I've roped a couple other people into helping me test and not a single one of us can call that number.
