Hello,
Our organization has one sandbox account (+12094974301) but we cannot receive or send faxes using this account.
Since I need to create an application that sends and receives faxes I could not use this sandbox account, so we added an additional number (+14242915868) in the service portal that can send and receive faxes.
The problem is we cannot create Apps using the new number because our sandbox account is associated with the old number and there seems to be no way to create an additional sandbox account for the new number.
How can we either configure our existing sandbox number to send and receive faxes or associate our new number with our existing sandbox account?
Thank you.
