Small adjustment for the verification code example

[RaxCore]

The problem

Hi, I successfully tested the registration using a voice callback with this nice documentation, but in the last segment of the following line, the hyphen has to be removed to get it work:

original:

curl -X POST -H "Content-Type: application/json" 'http://127.0.0.1:8080/v1/register/+431212131491291/verify/123-456'

working: curl -X POST -H "Content-Type: application/json" 'http://127.0.0.1:8080/v1/register/+431212131491291/verify/123456'
