Texting is now randomly not working. We have used Zoom Phone for almost a year.

Hi there, one user is getting the error message, "You don't have a direct number. You cannot start a new conversation" when texting some people.  She can text some people from the desktop app, but not others.

• We have been using Zoom phone for almost a year
• We do have 10DLC and a campaign approved / assigned.
• The phone numbers were ported into Zoom Phone almost a year ago.
• We haven't made any Zoom admin changes in the Zoom dashboard.
• We don't bulk send text messages.  Just used in communicating with our customers and vendors.
• I've send a text message to a person that she can't and it works fine.

Any guidance would be appreciated.
